Everyone loves to play photo-psychic.
I think it is the 35mm DSLRs that have the evolutionary genes of a Dodo Bird, never mind MFD.
Little cameras are swarming at their heals like a gaggle of ninja geese ... enough nips and you bleed to death.
24 meg APSc cameras the size of Chiclets pack ... can FF be far behind? That's 36 meg in a pocket camera that can take Leica M lenses, (the next best thing to view camera optics) ... and these cams are getting their own set of AF optics.
I can see a future where there are two formats ... big formats for special niche work ... contemplative, zen experiences with photography. Or, go everywhere smallness that can shoot in any light, using any lens (if there is even a lens), and software that allows creative choice after the fact.
All the folks that will make this completely happen are in diapers right now ... and everyone who blanches at the idea will have their big brick of a Nikon/Canon 35mm DSLR bolted to their walker, or carved on their headstone.
