FF camera's other than the viewfinder, do not 'need' to be larger, at least with DSLR's.
Secondly, as long as they keep making crop sensors denser, as well as glass that can continue to resolve the denser sensors within the limit's of diffraction. Crop bodies will stay somewhat relevant from a performance perspective for niche markets, and a cost perspective for the lowest end market's.
Btw, what are the current diffraction limit's of the D800.. I think I heard F8?
By the time F4 becomes the diffraction limit on APSC, it's game over for APSC's 'reach advantage'. You would then effectively get the same reach with a 35mm lens.
The only way to get more reach would be to get a longer lens, and put it on a 35mm sensor as the diffraction limit would then be F5.6 on 35mm.
There is currently NO advantage to an APSC sensor Vs 35mm, apart from economic reasons, and possibly the size of lenses (the size advantage of the camera's themselves is mostly artificial).
The 'reach' advantage is over hyped as you do not actually get 1.6x the reach, as crop camera's are also 1.6x more demanding on the lens. Again it boils down to economic's, because if you actually needed more reach, you would buy the appropriate lens.
As time passes, and the silicon economic relevance mostly disappears, APSC will suddenly become allot less prevalent as 35mm sensors become the new marketing tick-box that a DSLR 'must' have.
With all this said, I'm not against APSC, and am actually very tempted by a X-pro 1 body!
