And if this is actually a "FF 7D," that just leaves one hole in the pro line-up: a high-MP studio cam.  Maybe that's the real 5D3, and this is the 7D2?

No if that was the case the 5D3 would be the Huge MP, the 7D2 would be the king of Crop and this would be a 6D or similar and be priced in between the 2.

HIGHLY unlikely.

Its more likely the 5 and 7 will merge, and they will make the XXD series the new 7D but with swivel screen.

That also then leaves room for the mythical 3D mega MP monster people seem to be demanding too. (although i can't see that happening either, if you want a high MP camera invest in MF instead).
Yes, i shoot video on a DSLR.

We all know 2012 is going to exciting year for all...... Finally.  I just hope they don't charge arm and leg for it.   :-*

...the lower end of the market is where there will be a shakeout especially with mirrorless on the way. the xxxxD xxxD and xxD line occupy a space that will really only fit one low end DSLR once the mirrorless moves in i think mirrorless will wipe out the xxxxD and xxxD lines leaving the xxD as the entry level DSLR with the 7D remaining the weather sealed crop flagship

Not to get too far off subject but I also like the idea of the xx00D being replaced by a mirrorless EF mount body, but I don't see it replacing the xx0D, Here's what I'd like to see for the EOS line: xx00D(APS-C Mirrorless)$1000, xx0D(APS-C Entry)$1000, x0D(APS-C Flagship)$1500, 7Dmk_(APS-H Sport)$2000, 5Dmk_(Full Frame Studio)$3000, 1Dx_(Full Frame Flagship)$6000.

To get back on track, if 5Dmk3 is the new Studio Cam, I doubt it would be 7.5fps; I believe it will have 22Mp but with something like 4fps and though I hope for a Pro-AF system I don't expect it on the 5D, I expect something like 9 cross-type AF points.

I have to say, I did not expect 7.5 FPS. I think I'll buy one... maybe two.

If you buy two you could get 15 fps, you just need to practice your framing by feel instead of by sight. And if they're $3K a piece you'll save $800 and get 1 fps over the 1D X.

A waterproof case company that is leaking something, that sounds bad.

Excellent point. You would also get 44mp. Take that D800!

;D That sounds really bad - but see, a Canon photographer in Kenya gets "shot" too, doesn't that sound bad too?
And both do this with such a nonchalance as if there is no NDA in this world.
I am with Arkarch - the camera is done, the rest is a theatre stage... Enjoy the epilogue !

Here's my "top secret" leaked spec list.

The 5DII replacment body will be:
Black or black-ish
Take still pictures, and probably video
Will most likely not use film
If digital, I have it on good authority the sensor will be larger than m4/3, but smaller than 645
Feature Auto-Focus
Will probably be EF mount
Will almost certainly be branded as Canon
Might have some type of removable flash memory based medium for picture storage
Will prominently feature button(s) <-note the plural, for key functions like taking a picture or changing setting

You heard it here first folks...   ::)

+1

Any other news that are in the "rumour" department should NOT be believed. This post should be a CR0 as someone has put it. never believe in rumours.

5Diii - 50D - 100mm f/2.8, 85mm f/1.2 vii - 50mm f/1.4, Sigma 35mm f/1.4, 20mm f/2.8, 70-200 f/2.8 vii - 100-400mm f/4.5-5.6L IS, 430 EX II, YN560, YN568, Bowen's 500R's

Well Said!!
Then let's hope Canon can release a 8-600mm F2.0L IS weight less than 350g cost $500 ;D ;D

The implication is that based on this rumor, you expect it now?   ::)

18 MP x 12 fps / 2 Digic5+ = 108 MP/s per chip / 22 MP = 4.9 fps (or 5.7 fps for JPG).  7.5 fps means dual Digic5 at least.  IMO - unlikely.

You didn't calculate that right. I'd say it's more like 18MP x 14 fps / 1.5 (since they do NOT get a 1:1 digic:speed ratio) / 22MP = 7.6fps.

(Or 50D speed at 27MP and some other data hint at support for perhaps up to 32MP at 50D speed.)

And also don't that dual-digic wouldn't be impossible, the regualr digic chips have all cost nothing much, even the lowest priced P&S has had one. Maybe digic 5 in plus version costs a bit more but still. 7D had dual digic. At worst it wouldn't raise price much from the extra chip alone itself. More expensive are faster shutter/mirror box or perhaps extra amounts of fast buffer memory and such, but most of all probably say a 4fps vs an 8fps FF mirror box is the real cost.

Let me throw-in my calculation.
In image processing algorithms such as ones used in cameras we do have linear scaling. So adding second CPU gives almost 100% more processing bandwidth. In most cases workload distribution is extremely  simple - schedule processing to first free CPU. In short: two Digics - twice FPS.

Since 1DX has 14FPS (with mirror lockup, see here) and 18MP it means that one Digic5+ can do 126MP/s (=18*14/2).

If 5Dmk3 would have 22MP with 7.5FPS it would need 165MP/s. It's either two Digic5+ (not probable), significantly less per-pixel processing (even less probable, since processing is done in ASIC it would new Digic HW version) or either MP or FPS is incorrect.

Just for comparison: using 18MP sensor with one Digic5+ gets 7FPS which is optimal from development point of view (reusing sensor from 1DX and one Digic5+).

Nope, check out all the past cameras generations and you'll see that adding a dual-digic in all cases only gave 50% rather than 100% boost.

Why not - the cheap 7D has dual processors??

[I suspect that the company in question would have known this, they would have counted on it, and not allowed the leak (which is why I clearly cannot choose the wine in front of them; dizzying, isn't it?).
I'm rather surprised no one's remarked on the Princess Bride reference.

Inconceivable!

We don't know the maximum potential of the processors. The 1D X is only telling us a minimum power the processors are capable of. Even if there are two of them in there, it doesn't mean you have to use them to 100%. There *might* be enough power in a pair of them to cope with a hypothetical 22MP at 7.5fps, and they just have some processing power left over on the 1D X.

Assuming the body as 22MP at 7.5fps, is this close enough to the "3D" people want? Assuming the AF is up to scratch of course. You can add me to the camp of why 22MP if they already done an 18MP FF sensor, unless it is to help prevent the deep pocketed uninformed from MP confusion with the lower bodies (18MP APS-C)?
