>>3380542>>3380557Don't worry boys, Sony got this one in the patents.
Foveon is the future. It looks like they are co-developing Organic sensor + Foveon at the same time, swatting both flies at once.
The interesting part is the order of the colour filtering.
Sony is going Green -> Blue -> Red
Sigma is going Blue -> Green -> Red
This is most likely related to the Organic layer which needs to be Green, it fits at the top above the non-organic stuff.
