IF the 7D is still selling well, why create a new one? What is Canon's motivation?
(This coming from someone who'd like to see better image quality from any new 7D design.)
I believe the most complaints were about the 7D's image quality, particularly its JPG engine. For example, the image processing done by the little EOS-M is far superior to that of the 7D, for both video and still shooting (at least that is what people are observing).
If a "5D3-like" AF system is put in a new 7D body this will likely bump the price to nearly $2K and probably even higher. Remember, the new AF system in the 5D3 essentially cost buyers about $1K.
To keep the price down and to address the biggest problem, I'd vote for better image quality above all else. If the 70D sensor can deliver that, great. If not, a better sensor is needed. I'd love to see a better focusing system in place, too, but I think we'd see a $2500 price tag for such a body. (I'm anxiously awaiting tests of the 70D sensor to see how well it performs.)
Canon will want to see a lot of 70D early adopters between now and Christmas. As such, I do not believe we'll see a 7D2 this calendar year.
