Good observations. As to your final point of Sigma developing a 15MP FF Foveon sensor, it is not unlike the Canon  5D and 5D2. At the pixel level the 5D is sharper and some think has "better" color than the 5D2. I have both and happen to like the "look" of the 12MP 5D better than the 21MP 5D2. I can't quantify why. However, to your point, the 5d has 8 micron photosites versus the 5D2's 6 micron. The advantage of more pixels is very pronounced when making large prints or when their is a need for bigger prints from crops. I'm not sure how receptive the market would be to a resolution trade off.
