Can any new high MP Canon be a full-featured professional camera, like the 1DX, and still compete on price? Wouldn't that leave the field open to Nikon and the D800, at a much lower price?
I decided to stick with Canon because I have a few lenses that seem just unbelievably good to me, that I don't want to take a chance on parting with, even if I could replace some of them with equivalent Nikon models. Who knows what you are going to get? But if a new high MP, high feature, Canon body turns out to be ~$7,500, then that makes the choice for me, and it's off to Nikon.
I could see a high MP body with 5D3 focusing, or even with fewer focussing points, and optimized live view focussing (at least as good as 5D II now). And if you can, give me ISO 800 that's as good as ISO 200 (or 100!) on my 5d II. After that strip out whatever it takes to keep the cost down. If I have to stretch to $4,000, I'll grit my teeth and do it. More than that, why not switch?
