What I think the Nikon market needs now and is asking for (by quite a few) is either a real D700 successor or a true downsized D4 ..both being accomplished in a single body. From a marketing point of view, I think Nikon would have the sales numbers they are looking for if they designed a D800 built body with their latest designed AF system, AF sensors spread out across the frame, 6-7 FPS, maybe a built in vertical grip (or make it optional...whichever the way the market dictates) and a fast processor....and price it around $3500.00 . One could look at it as a D700 successor and others a real downsized revved up D4. A number of markets, both pro and advanced amateur would be addressed. My 1.5 cents.
