I have seen it written that there is still an SNR advantage to be had in CMOS, but it is nothing like as large as for a CCD and it tapers off even more as your binning increases. What it would mean (I presume) is pixels small enough to have a well sampled image at short focal lengths with the ability to bin the output for long focal length scopes without a penalty to pay in terms of SNR, and the advantage of not producing bigger than necessary file sizes. With a cost penalty of course.
