Photoshop 10bit support

What would you require that functionality for? 16pc and 32bpc already far exceed those specs and even though they are dithered down to be displayed on your LDR devices, that should be more than enough to work with. Additionally, 10/12/14bpc support would only make sense, if you worked with a file format that also stores that info natively as well as requiring a whole lot of other magic in the color profile engine, the print engine, filter handling and so on. So by all means, this is much more complex than just shuffling around a few bits and bytes in the display routines, which in turn means it's not coming any time soon. Definitely not for CS5 and most likely not for CS6, either. You have to understand that any software vendor will have to weigh the development effort agains how many users would actually benefit from such a feature and currently that is probably only a fraction of a percent, so it is not a must-have feature. This may change as wider gamut devices become more affordable and thus more widespread used as well as OSs supporting them, but for the time being it is something most people have no need for.
