For me personally, I would absolutely purchase a 5D Mark III for ~$3500 if it comes with 7D AF, even more robust construction, 5 FPS, and some improved video capabilities. A 2/3rd stop improvement in noise and bump in dynamic range should happen as well. Can't wait for the new telephoto lenses to drop first, whatever the manufacturing problem was it sounds pretty major if its holding up the entire canon lineup
This is exactly what I am expecting but with 4fps and doubts about the price. I think it will be available late 2011 or early 2012.
I like Canon strategy of replacing their cameras position, similar of what they did with the 60D. Cameras are finite. What I mean is that there is no need to bypass our eyes resolving power, or our maximum functionality needs. A PC is never fast enough, but there is a limit of what we need from a camera. If the AF can track servo without a glitch, in low light, how it can be improved ? Clean ISO 204800 is not enough ? Even resolution has a limit for whatever size of print, since our resolving power, angle of view, print size and distance are all related. I am assuming you won't watch a print by turning your neck to view the borders

Therefore, since cameras are finite, how could canon improve the 5DIII without damaging the 1DS series ? Only by merging 1DS with 1D with a price a bit above the 1DIV. They can't force the current 1D pro users to pay much higher prices. It is a possibility that the new merged 1D to be an FF high res camera with 5fps, with 1.3 crop ability reaching 10fps? With this, canon can give the 5DIII a 7D AF without a problem, since it will still be a 4fps camera, without special functionality and durability of the 1D, and the price difference with the new 1D is smaller too. The more we get near the limit of what we need, the more the prices will drop. The 60D is an example, and I feel the new 1Ds/1D will be next. I have doubts about the pricing of the 5DIII.
This is just what I am predicting, but I am 100% sure that I will get the 5DIII
