It's a 19.x megapixel sensor (spatial) so 2 x that is 38-39 MP. Sigma says it's 39 megapixel equivalent so that makes perfect sense (2 x 19.x).

However, they are now interpolating color- the Green and Red layers are 1/4th the resolution, while the Blue keeps the detail layer. Interesting indeed- so they are aiming to decrease the green & red noise layers while the blue which is the first layer and the one that was less prone to noise carries the detail.

I don't think its accurate to say they are interpolating, they are simply using the same existing data more than once. Interpolating implies filling in information that is missing. This is not missing information, its multi use information.

For B&W this may be great. For color, I want to see how it looks- it's not X3 anymore like the previous Foveons per photo site, but only for the blue layer. The interpolation should still be better than typical Bayer though.
