Absolutely - and that's exactly where Canon has stated they are positioning this lens.  I have to assume there are quite a few xxD, 7D, and even some Rebel owners who want to step up from the base level (55-250/75-300) or mid-level (70-300 non-L) to a better quality telezoom, but then look at the 70-200L's and figure they're not long enough, and look at the 100-400 and think, "I can't lug that beast around!" 

It's still definitely a compromise lens, but with some very reasonable compromises.

Yep.  If you are only going to buy and own 1 telephoto "L" lens you are going to have to make compromises in which lens you buy.  I see this lens taking a lot of that market.

Sigma's non-stabilized 120-300 f2.8 lens sells for $3,000 street. That should give a rough idea of what the stabilized version is going to sell for.

However, its size and price (and the 2 stops extra) put it in a whole different market. I can see myself put a 70-300L in my backpack (like i do now with the non-L version) as an allround tele, but lugging that 300 2.8 around would probably break my back(pack).

Bump with yet another challenger....Sigma announces stabilised 120-300mm F2.8 telezoom

I don't know that I'd call it a challenger to the new 70-300mm L.  As Canon stated, "Users looking to a camera like the EOS 60D or 7D often put a priority on reasonable weight and good handling, and this applies to their lenses as well as their cameras. Until now, Canon’s long zoom lens options have meant either putting up with lots of weight..."

The current non-OS Sigma 120-300mm f/2.8 is as long as an extended Canon 100-400mm and it's twice the weight.  Even if Sigma can add OS without adding to the size/weight, the Sigma lens is still big and heavy.  That's not really the market Canon is going after with their new lens.

If the reportedly slow AF in the non-OS version is is carried through into the new OS version, I think the Canon 300mm f/2.8 would be a better choice, and likely there won't be too much price difference (relatively) between the new Sigma OS zoom and the MkI version of the Canon prime.

there's almost no relationship between the new canon 70-300 L and sigma's 120-300 f/2.8.  just in terms of handling alone, that's like comparing sneakers and hiking boots.  one is a lightweight, do-all lens, the other is a beast meant to shoulder a specific burden.  very different people will be looking at these two lenses for very different reasons

Yes, I realize that.  In this post I'm not focusing (as usual) on Canon's market positioning, I'm focusing on what will be best for me.  Apologies for not making that clear.

From my perspective, the 70-300mm has a nice focal length range and features, but the maximum aperture is narrow.
The 100-400mm I'm less interested in on the basis of its being an older, heavier, and more expensive design all around, without the benefit of a zoom ring (well, it's a benefit in most situations, plus the dust advantage).  I didn't realize until writing this post that the apparent 1/2 or 1/3 stop benefit of the 70-300mm is negated by 155mm, and the 100-400mm surpasses it by 228mm, where it holds on at f/5 until 239mm, where the 300mm has has given way to f/5.6.  Not a shattering victory and in actuality a rather small range where the 100-400mm is faster, but the 70-300mm isn't an unambiguous improvement.

Size and weight for the 70-300mm doesn't really sell it to me over the 100-400 - minimum focus is considerably better, however.

The MFD charts (comparing the 70-300mm and the 100-400mm product pages) are somewhat ambiguous to me because I'm left attempting to compare different focal lengths:

The 70-300 does seem to start better at the center for many focal lengths (especially wide) and keeps that improvement to 20mm diagonally (where one of the f/8 30LP/mm lines drops off, though the other stays high).  The 100-400 MTF lines, sharpening up by 400mm compared to 100, suggest to me that it gets sharper (relative to its wide performance) as you increase the focal length, whereas the 70-300 seems to be the reverse, being sharper at 70mm than 300.  Unfortunately this doesn't help a direct comparison - the MTF lines for the 100-400mm sag at about 5-10mm across the frame, at 400mm, but that's apples and oranges to the 70-300 @ 300mm (though it bodes well for the 70-300 that its lines don't sag, but stay high farther across).

I'm starting to think that overall the 100-400mm may have no great handicap at comparable focal lengths, if not an edge...really the only thing that stands out is the rather ugly 80% contrast for 30 LP/mm lines (the thicker / coarser lines) on the 100-400mm at 100mm, but it stays at 80% further across the frame whereas the 70-300mm drops rather quickly past the corners of an APS-C frame (unfortunately, comparing 70 and 100mm, so apples and oranges again).  How the newer coatings etc. of the new lens enhance the performance indicated by the MTF charts, not to mention performance on the targeted APS-C frame, may make up the difference remains to be seen.

In any case, the new 120-300mm looks like a potential deal buster to me - if it is more appropriate for full frame is no problem for me, since that leaves full-frame camera options wide in the future.  Overall contrast and sharpness, features, and especially AF reliability all remain points I'm worried about, however.

Thankfully I can put off a decision on these zooms for some time.

mmm... I wonder if anyone mentioned this before, but another reason why the 70-300L won't fill the niche of the 100-400L is that it does not support the use of extenders.

At least the 70-300L is not listed as one of the supported lenses under the EF 1.4x III extender description on Canon Japan's website...

Yeap, it's been pretty well determined that the 70-300mm won't work with extenders.  This confuses folks because the new 70-200mm IS II does.

Good points, Ed.  There are trade-offs between the two lenses, certainly.  IQ-wise, my guess is that in general the new lens will be a little bit sharper on average, but the 100-400 is plenty sharp.  As you state, the aperture differences are not major, and frankly both are slow...  So in my mind, the main differences come down to portability and weather-resistance vs. the extra 100mm. 

Minimum focus distance (MFD) is considerably closer (6') with the 70-300 L, but maximum magnification (MM) is not too different.  It seems that the new 70-300 takes focus breathing to the extreme - the MFD for the new lens is the same as the MFD for several of the 70-200mm zooms, and the MM at 300mm is the same as as those other zooms at 200mm.  So, if the numbers are correct (and apparently Chuck Westfall has confirmed them), the new 70-300 L at the MFD has an effective focal length of only 200mm. 

Sigma lenses are a mixed bag - AF issues do seem to be common with them, and focus is usually slower than their Canon equivalent. 

Yeap, it's been pretty well determined that the 70-300mm won't work with extenders.  This confuses folks because the new 70-200mm IS II does.

Part of the lens design, keeping it compact - the rear element of the 70-300mm is right at the back, so there's no room for the protruding element of the extenders.  3rd party extenders (e.g. Kenko) would work.

Good thing you're not in a hurry, and good luck with your decision!

Martijn, sigma make a decent 300 2.8 and 120-300 2.8, used they are bargains and offer really great quality for the price.

As for the 70-300L I am witholding judgement until I see results. With iso 1600 and 3200 being saleable settings these days I'm not worried about 5.6 so much (although not being able to use teles is a valid point). Im looking at this as a lense for when i dont want to carry the 300 2.8 and 70-200 2.8 about and be swapping lenses rather than as a direct replacement for any particular lens. I wouldnt be suprised if canon used this to delay or ditch a 100-400 upgrade. Other brands have managed to make good versions but canons was so/so. If its sharp at 300 @ 5.6 then it will probably sell. I was waiting on a 100-400 ii but this on a 7d is good enough if its sharp :)  I dont think canon are as crazy as it may seem. Now a 70-300 2.8 IS thats razor sharp would be worth some pennies !

I have the Sigma 120 - 300 f/2.8 and it's as sharp as a tack, also have the 70 - 200mm f/2.8 IS L MkII and although it's a little sharper it's not massively so.  The 120 - 300mm is the cheapest way to get to 600mm (with a 2xTC) and still retain auto focus.

Another lens I'm fortunate enough to own is the 28 - 300mm IS L and it's this lens I would recommend ahead of the 70 - 300mm IS L.  It's just as fast at the long end, latest generation IS and you gain the 28 - 70mm.  Image quality is well up to the mark, maybe it's not up with the other two, but why does anyone need to compete in the good, better, best race, when the good is good enough?

Buying this superzoom, although expensive could make most other lenses redundant, and the fact you don't need to change lenses means less sensor cleaning. min focus distance of .7meters and mag of 1:3.3 means a screw on close up filter makes macro possible.  It's also possible to use a TC if you are careful & don't allow the rear element to meet the TC !

All you need (almost) in one lens, and certainly one which shouldn't be overlooked (as superzooms often are).

Actually, it's one generation back in IS - the 28-300 has 3-stop IS, vs. the 4-stop IS of the newest lenses.

That aside, it's one big, heavy beast, and for crop body users, there no wide angle (45mm is 'normal').  I think I'd rather carry the 17-55mm + new 70-300mm and cover a broader range with a smaller and lighter package with a lot less weight for about the same price, or 24-105+70-300 if weather sealing is important.

But you're absolutely right that people often forget about this lens!  It annoys me when people state the 100-400mm lacks weather sealing because of the push-pull zoom design, when Canon's other current push-pull zoom, the 28-300mm, is weather sealed.

Take a 500 dollar lens and throw in AL-2 and IS and it is suddenly 1299-1799!

whoa, let's not oversimplify things.  the glass in this by far exceeds the glass you're getting in the $500 consumer 70-300 zooms.  take a look at the MTF charts.  or even take a look at real world images taken by a canon 70-300 non-L and compare it to something shot on a 70-200 L series lens.  that's the expected difference in image quality.

weathersealing is a big deal too and definitely worth a significant premium on a lens.  when I first saw this, I was scratching my head over the price, but after thinking about it and seeing what others have to say about it, I think this is actually a really well-priced variable aperture L-series zoom.
