We'll know soon if it's just for jpeg images (i.e., MORE NR) or true RAW files.

Anyway, I'm more curious if Canon has made any progress in the low ISO DR arena.

I doubt a new sensor and better ISO performance would only equate to smoother jpeg's. That's compression quality your thinking of.

5X faster in live view and good high iso?  Sounds like the next EOS-M will be a winner too!!

What about low-ISO performance (as in, dynamic range/read noise)?

True, but the "one stop better" in some previous models has been made in compression quality and not in the RAW files. For example, many initially were point out that Canon was saying two stops of improvement between the 5DII and 5DIII, yet, it was only in jpgs. In Raw files. it was about a stop or maybe a little less.

So, it matters where the improvement is made

Should mean better IQ for raw as well, obviously the quality of a converted raw depends on the quality of the post-processing and the quality of the person making the decisions.  Cleaner raw's would be good, as apart from low iso noise, I would be happy with the jpegs from my current cameras, the M is actually a step up in this regard, I still like to do a bit of luminance NR on the M's raws, just very slightly, otherwise they are usable out of the camera by any other criteria.

or finally (after four!! generations with the same sensor) a good rebel (750d/T6i) to replace my 400d ;-)

Is the lack of AFMA confirmed or are we holding out some slight hope for it to make a surprise re-appearance?

Well, that ought to DRum up some DRead from the DRoll DRones who DRool over DR, and DRag many a forum thread down the DReary path of DRivel, DRaining into puddles of DRoss.

 :D

Hopefully they improved the low ISO read noise but I'll believe it when I see it (and I really do hope we see it).  Don't worry about that shutting down the bellyachers though -- bellyachers are quite resourceful :-)  Funny post though.

I am very excited about this, not because I'm gonna buy the 70D but for what it means for the 7D2! I love my 7D too much to go sell it for a 70D, I wonder how many will though? I mean if that ISO is clean at even 1600 and good at 3200 it might tempt a few. I am finding that nowadays I end up using ISO 1600 a lot. I would love to just be able to leave the camera at ISO 3200 and just shoot all day, especially indoors, getting max efficiency from a flash too!

As has been said before, the introduction of the 70D is very exciting, particularly the clues it offers to the upcoming 7D2. Remember, canon said the 7D2 will be "ground breaking", not the 70D.... So whatever happens with the 70D is not " groundbreaking".

If new standard of iso performance and 5Xfaster live view focus in crop cameras is not "groundbreaking", then the 7D2 must be something to behold!

Good Point.  On paper the 70D has everything I would want in a crop body (as long as it has AFMA).

To improve on this my guess is it will be focused toward sports.  Maybe 10+ FPS, Totally weather sealed, maybe a 1d style body, Many more AF points, etc.

1. it's not even a straight rumour, but onl y a "hearsay rumor". :-)

2. just to get even with the Nikon D7100, the 70D will need:
a. +2 EV DR @ base/low ISO
b. AND 1 EV less noise @ Hi ISO (1600+)

3. compared to Fuji X (APS-C Trans Sensor) the 70D needs 3+ stops improvement in Hi ISO noise [see dpreview RAW comparison] 

So ... really nothing to get excited yet. AFter all, Canon has proclaimed "the future of photography" a couple of times already and then delivered only very minor improvements.  :P

well, according to what we have seen in the past years, the 7D2 (and few generations of rebels) will have the same sensor as the 70d..

I'm very leery of Canon's ISO figures, they are for jpeg images that are highly processed with lots of NR.  Their Digic 5+ gives them power to do a lot of good quality NR, but it does not boost the underlying sensor performance.  Still, any improvement is good.  They claim ISO 12800 (25600 expanded) which is definitely a stop better, but its for jpegs.
 
The native ISO of a RAW image is more telling.
 
I hope it has AFMA, without it, images using a 20mp sensor will not be as sharp as they can be.
