70D would pretty much have to supply at least 5fps to maintain its prosumer category which the 60D nearly lost due to lost features and downgraded handling.
7d2 can have the same AF as the 7D, it was good enough for most things once you figured it out, worked well in low light and action tracking. Adding ability to track the subject also using color cues from a more complex metering sensor would be a nice benefit to have to match some of the Nikon bodies.
but they'd better get rid of the banding and pattern noise problems for both new bodies, especially at low ISO. It's become a pathetic weakness already when competitors' cameras costing under $400, like the ultra tiny Pentax Q or D5100, can supply raw images without banding problems.
Same AF yeah, but what if they went with the trend and added the same AF as the 1DX/5D3 ?? Now, I don't know how that would affect 1DX sales, but if it would then the 5D3 would be killing off the 1DX more, people will get a 1D because they need specifically that, and a 7DII like that would be killer~
But anyways, the 60D was a failure and only survived with by slashing down the price immensely, and it's flip screen was nice... that's about it, no AFMA, not a significant AF or FPS or Sensor that makes it any more than a rebel.
Will the 70D change that? I sure think, and hope it will, because the 7DII will likely cost around 2,000 and the 70D will be the in between model at say 1,200? But rebels are quiet expensive on release.... *sigh*
