So for the people who the 7d mk II is aimed at those FPS / AF advantages plus the reach are going to be worth paying a premium for. The "quality" of their images will be better via a different route.
True, but the same is true for the wedding pros wanting good low-light performance, which a crop body can't deliver. When one product is clearly better than another, you expect it to have a higher price. When two devices have clear trade-offs, where different purchasers will prefer one over the other, you expect them to have similar prices.
I realize Canon has a tendency to overprice their product launches, with the understanding that prices will fall by 25% within the first year, and maybe that makes sense if their design is flawed, resulting in poor yield for the first few months of production, but otherwise it makes little sense. The market has spoken, and has determined that the current 7D is worth about $1300. A new model should be priced in that neighborhood. Otherwise, sales will suffer. $1500 seems like a sane markup. $2200 would mean that they won't sell any of them.
There's simply nothing they could add to a 7Dmk2 that would make it worth more than a matched pair of 70Ds with one lens. The 70D is too good. It's so good that they had to remove the 60D and 70D from CPS to avoid completely cannibalizing the market for the 7D. And the 7Dmk2, sensor-wise, will just bring it up to par with the 70D. I doubt it will have much better FPS than the 70D, and the 70D's AF is already very, very good, so it's going to be hard to justify a huge premium there, too. And the 70D comes in at about a grand....
Honestly, it will be hard to justify $1500 for most people. $2200 is right out.
