Its clear that neither sensor type is a-priori better than the other. There are always trade offs. For Leica cost is less a factor so they concentrate on other areas. Canon and Nikon are in a much more competitive environment so they have to squeeze out the most bang for the buck. Pixel density is always a concern, but its a moving target. Moore's law says we double chip density every year and a half or two years. That's from a manufacturing point of view. To some degree it seems that the newer imaging chips can stand a higher pixel count with the same or better noise. The D40 and D40x were not too far away from each other generationally, so lower noise performance was the tradeoff for more pixels. In the same vein the Canon G11 got better noise performance than its older sibling the G10 which had more pixels. It will be interesting to see how the new D3100 and D7000 compare with their elder brethern when they come out.
