I do like the 21mp number better than 24 for APS-C... I personally have no problem with 18, but I'd be OK with 21. I'd certainly take 21+less noise over 24+more... I'm not trying to print 48" wide.
AF and most of those features sound to me like a 70D. And I think releasing this camera as the 70D would set up good things for a 7d2 to come later. In fact, depending on prices, I might consider this over a 7d2, which I'm sure would be a dream to use, but might be more camera than I actually need.
The spec that gives me pause is the 10fps. Now, if they can make the 7d2 do 12 (or, dare I suggest, 14), then 10 makes sense for a 70d. But then the 7d2 is encroaching on 1dx territory. It would make a lot more sense to me as a potential 70d if it had 7-8 fps, leaving double-digit fps for the professional cameras.
That said, if this is the 7d2, I wouldn't swear off it- I'd just wait till the prices came down to what I paid for my 7d, and pick one up then!
