My crystal-ball tells me, that the 7DII will have a similar price tag as the 6D had at the beginning (2000-2300$), the 70D will come out somewhat below of what the 6D is at that time (1300-1500$). Both will be APS-C and maybe even share the sensor; the 7DII will have a much better AF-system and higher frame rate...
...The new APS-C senosr are damn good, and if Canon manages to make an even better one than Nikon has, then I don't see the reason to go FF. Especially since it is not only the camera that costs a little more, its just everything that gets more expensive (24-70 f2.8 of f4 lenses for 2000$/1400$, more expensive filters, a heavier and more expensive tripod do manage the aditional load)
My crystal ball says pretty much the same thing. I expect the 70D to come in at about the same $1,200 (U.S.) range as the D7100. That still leaves plenty of room for the 7D. I expect price at introduction to be about the same as the 6D, but they could well hold it to under $2,000.
Only question I have is whether or not they will share the same sensor.
With three sensors for three full frame bodies, there is some reason to believe that Canon could well put different sensors in the 70D and the 7D. (Perhaps a 24 MP sensor in the 70D and a 20 MP sensor in the 7D that offers a little less noise at higher ISOs.)
I think if we are honest, the new APS-C sensors are (will be) good enough for 98% of the people, no matter if there are 1500$ FF bodies or not.
For most people Full Frame makes no sense. But a lot of Very Serious Photo Enthusiasts think they need Full Frame. And CaNiSony marketing wants you to buy FF.
Do you shoot landscape and print really, really HUGE Then you need something like a Nikon D800E. At 13x19 even a pro-pixl-peeper will have a hard time telling what camera was used (M4/3, APS-C or FF).
But people have the right to buy what they want and not what they need.
I agree with both statements. In fact, I think they are a little conservative. The advantages of full frame sensors are purely in the margins (high ISO, wall-sized prints, extremely narrow depth-of-field shots).
I never understand those who think that one format will supplant the other. It's like suggesting that a four-door sedan makes a sporty two-door coupe obsolete. Different models, different purposes. No doubt People fail to understand that Canon and Nikon don't want us to pick one model over another, they want us to have one of each.
