There is a lot of R and D in CMOS and it will show at some point. Perhaps not yet though.
Fuji have an organic sensor which is supposed to have greater dynamic range (15EV compared to about 12 on some of the better DSLRs).
Sony have a curved sensor which makes corners 2X more sensitive and the centre area 1.4 X more sensitive. Expect to see that in a camera this year.
Sony also have a Foveon style sensor where the pixels are at different depths to get the colour rather than a colour filter array.
Sony already are using back illuminated sensors that are 40% more sensitive (largest being a 1 inch diagonal sensor).
There are other developments happening as well. So it all adds up to a dynamic area that could filter down into astroimaging if any of these improvements actually challenge CCDs (it would have to be a big leap).
I can't see that happening anytime soon but perhaps another few years maybe. CCDs seem to be stagnating at the moment and Kodak sold their sensor division to True Sense imaging who didn't really bring anything new and have since sold it to someone else. So a very stagnant scene.
Perhaps CCDs are being passed by for the more favoured CMOS in most applications, no doubt driven by cost.
What is the market for CCDs anyway? Xray machines?
Even Leica who used to use CCDs in their cameras have switched to CMOS.
