Hmm you guys should look at this DPReview comparison between G10 and Canon 1000D:
http://www.dpreview.com/reviews/CanonG10/page20.asp
G10's pixel density is much greater than 1000D or any other current APS-C / FF sensor, but its 14.7MP still provides a real resolution advantage over 10MP APS-C sensor. I think that shows that the pixel densities where we stop getting any advantage from increasing number of pixels is is still far away.
At high ISO though the G10's extra resolution gets eaten away quickly. And thats pretty much the reality of high MP sensors in general. You enjoy the extra resolution at low-ISOs where the per-pixel SNR is good enough to make those pixels useful. As you go to smaller and smaller pixels the per-pixel SNR will go down and the ISOs at which you can enjoy the extra resolution will go down as well, until you hit a pixel-size where even at base ISO the SNR is low enough to be not acceptable.
