Not that I wouldn't like to see a Nikon with a Foveon sensor...

I wouldn't. Something that like a Foveon in concept, but better in
execution, yes. I heard rumors early last year that Oly and Canon were
working on a layered pixel sensor, independent of each other, but I've not
heard anything since.

Measuring three colors at each point costs you sqrt(3) in dynamic range and
noise and makes raw files three times larger.

The math tells you that the actual increase in luminance resolution is tiny,
and the physiology of the human eye tells you that only a Foveon-equipped
robot could actually perceive the difference in color resolution.

Basically, measuring three colors at each point really isn't a good idea.

Inversely, the Bayer idea is one of the most brilliant ideas of the 20th
century. And all people do is complain.

it would be great if it could be done without compromising other
aspects of the image. so far that's not the case.

the only advantage a nikon (or other mainstream brand) would have is
that the camera would be competitive in features and speed and it could
accept a wider variety of lenses and accessories.

mainly because they don't understand how it actually works.
