Colour moire with Bayer cameras comes mainly from having different nyquist cut offs for the different channels. If the channels in the new Sigma sensor are no longer equal that must carry and increased risk, surely?

I would think not you probably will get "colour crawl" but no colour moire actually it makes quatro foveon behave more like human eye which has b&w resolution about 4 times higher than colour one. Just for curiosity i took photo made B&W layer pasted in new image, scaled color image to 50% pasted as a new image scaled 200% all linear merged with B&W. Set opacity 50% for B&W and adjusted saturation.
