Re: Will you buy if Nikon went crazy high ISO & not MP?

So let's assume the D400 comes with say 12 MP but say up to 51200 ISO and very fast FPS (may be more likely 25600) - would there be more demand for it than for another D7100 like camera? I don't think Nikon will go that direction - but just think of the possibilities for wildlife or sports (both areas users may want pro DX camera) - you could get away with a reduced need for a fast telephoto like a 200-400 VR and make do with an 80-400 AF-S. Of course the other part of the pro DX market - the "crop away to glory" market will be not satisfied.

Are you working under some assumption that a 12MP sensor would have less noise than a 24MP sensor when the output of the two is viewed at the same size?  That doesn't seem to be true these days with Nikon's full coverage microlenses and other pixel tech.

Agree - that's not completely true - and more of pipe-dream specs. But on the other hand D4 goes to 12800 native ISO while the D800/D600 top out at 6400 native ISO.

A 12MP sensor would obviously have the ability to process more fps (but the mirror would have to be able to keep up - if there is a mirror).

I'd be extremely surprised if Nikon ever made another dSLR that was 12MP.  They seem to be showing that everything is at least 16MP and, except for the D4, everything else is at least 24MP.

FYI, aperture on a lens isn't only for keeping the ISO down.  In my soccer shooting, I always shoot my 200-400 wide open at f/4 to help with subject isolation vs. the background.

Sure - one huge use for the f/4 @ 400mm for 200-400 f/4 will be subject isolation - but on the other hand if its just an extra stop of light needed in some cases - the 80-400 will do just fine with a lot less weight. Also subject isolation is not a complete lost cause at 400mm with f/5.6 (especially at nearer distances).
