What I find clear from this conversation is that two 5D sized cameras are needed. And not because they are actually needed IMO, but because that's what people seem to be demanding.
One group wants 36mp FF images, and are saying they care about that more than bleeding edge ISO performance, which became possible by keeping the pixel size larger which requires lower mp total. This same group doesn't seem to care about video features either. Makes perfect sense then to just give them what they want... Maybe this can be done cheaper, perhaps not. I suspect there is very little if any actual cost savings here but perhaps there is a way.
Smaller form factor 5D sized body with ISO improvements and improved generation 2 video, in FF, and you have the other group covered nicely and I suspect this is also what all the 'new' customers that gathered to the 5D out of no-where during the video boom and others as well have come to expect out of a next-gen replacement.
Between the two, I'll take the second one. I don't care if it comes out in early 2012 or not for another year, that bit really doesn't make or break anything for me.
Problem solved, close the conversation. lol.
