28 MP APS-H, usable ISO 6400, 8 FPS + EF-S compatible in 18MP crop mode with 10fps
APs-H? Now come on, you know that ain't happening, it will be the good old 1.6 crop.
Also, a jack of all trades camera like that would compromise on certain things. With such a huge file size 8 FPS is dreaming.
I'd much rather it be specialized ---optimized for whichever direction - do you want speed and high ISO, or big MP's? Canon does need to get a slow camera out there, optimized for IQ and low ISO performance (the good old DR debate), but that most certainly ain't happening if you go jack of all trades. Again, the 7d was very popular among sports and wildlife shooters, where FPS and ISO capabilities rule. the other camp is those stepping up from the rebel bodies but don't quite have the budget to go FF. I was one of those users, and while I loved the 7d for the time I had it, it wasn't the camera I needed.
The next 7d will mostly be a baby 1dx, lower mp's, high fps, some form of the 1dx AF, and much better performance at high ISO's.
