The older DP series cameras used (I think) a sensor not too different from the one in the SD10. Excellent color and not much edge-roll-off, just sharp three color per-pixel definition.

Yes, they had the DP13 sensor - same as the SD14/15 cameras but with different micro-lenses and a built-in UV/IR blocking filter.

In theory the sdQ on lo-res should behave somewhat similarly, but, in terms of reality I'm not so sure about that.

Nobody knows for sure (meaning no Sigma references) how they do that.

You would think that they use pixel-binning 2x2 on the top layer and pre-Quattro raw conversion but that has yet to be proven to me.

Oh my, I didn't quite understood anything

Xavier una vez más:

It all depends on what is meant by "not too different" ...

For example, the DP1s and SD10 sensors are the same size (20.7 x 13.8mm) and both have three layers.

But they have a different number of pixels, different fill factors, different micro-lenses, different firmware, different UV/IR blocking filters, different raw-to-color conversion multipliers and . . different sensor part numbers and data sheets.

Are they "not too different" or are they just "different"?

P.S. For "pixel-binning", please see: http://www.foveon.com/article.php?a=71
