The point is that the more photons you capture, the less noise you get.
Assuming the Foveon wastes the same percentage of its area on interconnect
as a Bayer pattern chip, the Bayer chip will filter out all the "wrong"
color photons that hit each sensor, while the Foveon will actually use them.

But it's a different fabrication/sensor technology, so you don't know how it
will compare until you try it. And the SD9 isn't all that impressive in
either sensitivity or noise.

Obviously, implementation matters. But I see no reason to expect that a
Bayer pattern chip is intrinsically better--it's just been worked on longer.
<<<<<<<<<

This is exactly right. There's no reason to expect that a Bayer pattern chip
is intrinsically better. There's also, so far, no proof that the Foveon chip
is enough better to be worth the hype.
