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.
