However, Brightcolours has made the interesting point that reducing noise or increasing pixels might end up leading to the same place. And if we had mega-resolution sensors, we could certainly throw away the AA filter, nice.

If I understand you correctly, you mean down sizing pixels would provide so very small picture elements that we wouldn't be able to see the jagged edges (which are actually not there in the real image source), and we can easly get rid of the AA filters. If so, isn't it again a matter of magnification? I think this is only valid for very large prints, right?
Would be nice, but see my comments below...
Yeah, they can keep the increase of pixel density up to a certain level, but make more efforts for; increase in dynamic range/color quality with higher ISOs, improved AF and metering in low light, better auto WB, 100% viewfinders with sensor cleaning for all, improve micro lens and photon collection technology etc...

Quote:To be specific, if my camera had a 200 megapixel sensor with the same per-pixel noisiness as my current Nex, maybe it would indeed be usable at much higher ISO right now. Because I could down-sample the image to one-sixteenth size and get rid of a lot of noise.

Interesting arguments. Would not shed a tear if all APS-C sensor developers drew a line in the sand at 24 megapixels (something like 18x24 inch final prints at 240 dots per inch) and said "from here on in, we're only increasing dynamic range and usable ISO levels, or switching to Foveon-type no-color-filter-array technolgy".
