Now you're talking about something real. Ignoring file size inconveniences, if the frame rates you need are attained, there are always definite advantages to more pixels. Firstly, there's some resolution at which AA anti-aliasing filters become irrelevant, am looking forward to getting rid of that anachronistic AA kluge that makes up for the fact that our sensor pitch is not a lot smaller than the lens resolution. Throw away the AA filter, and you get an immediate (admittedly modest) step up in max image clarity. Obviously only noticeable with great lenses.
Secondly, how neat it will be to flip a switch and read out our sensors at "full" (say 48 megapixels on APS-C) resolution and also at "binned" (12 megapixel) resolution with nicer color fidelity and half the noise.

You can't bin red and bleu too and still get 12mp... you are only binning for less luminance noise here. Which of course is a plus... but you can still get about the same values of red and blue chroma noise with 2x2 pixel binning..
