Should Sigma make a 30 MP per layer full-frame Foveon instead of 20 MP per layer?

As much as I would love more pixels than 20mp I would not want them at the expense of overall pixel quality. Having owned all SDs from the 10 to Merrill I've noticed how the 3D look and color saturation have struggled to maintain the original feel of the SD9/10 as the pixels got smaller. I'm not privy to the actual Foveon technical details but I have a feeling that there is a limit on how small the pixels can be made before the decreasing s/n ruins the Foveon look.

I was hoping the FFF would have 24mp just for marketing purposes because it would be the same as the Sony and other FF bodies and so not sound inferior to potential new buyers.  But an eventual 80mp/20mp Quattro design could compete with any FF camera, at least in resolution, provided Sigma can control the heat and processing time.

You also need to remember that the higher the mp count the greater the chip reject rate which in turn raises the cost of the camera, and if the body it too costly very few will buy it.
