Small pixels mean higher noise, lower sensitivity, lower well depth (how quickly they overexpose) and poor matching of optics to seeing for the average user who has average to poor seeing.

Greg are you reffering to mono only? Sony make a 14.2 mp chip with 5 x 5 um pixels, the ICX 453 has 7.8 x 7.8 pixels, ICX 493 has 6 x 6 and ICX 429 AL has 8.6 x 8.6. The Sony chips are much cleaner and many users don't bother with darks, it is the Kodak chips which have a lot of noise. If Kodak does go down the Sbend I imagine sony would pick up the slack anyway.
