Sigma unveils radical DP2 Quattro with re-thought ~19.6MP Foveon sensor
It looks like now they are moving to partial colour interpolation now:

It probably means lower colour resolution over the previous generation.
The 4:1:1 B:R:G arrangement makes it somewhat closer to a Bayer sensor TBH as that has 1:1:2 B:R:G arrangement,although each group of 4 B photodetectors has a dedicated R and G photodetector.

I really like what Sigma are doing here. I guess you could argue the merits of Foveon, hybrid Foveon and Bayer sensors for long enough, but the fact they have broken away from everyone else and tried something new should be applauded.
The same goes for the styling of this thing, I'd love to get my hands on one to see how they feel.

It's kinda interesting....
Still trying to think in my head how having precision only in one channel will effect RAW rendering, because Bayer is ment to be more akin to how we view the wave lengths, the human eye has a big gap for blue wave lengths compared to the others.
