I've tested the Nexus 7, several of the players can decode (seemingly software decodes) 720p 10bit MKVs without much trouble, the 1080p works on some players but others struggle. There seems to be some optimization necessary for the new Jelly Bean but I'm seeing a lot of promise for 10bit.

Edit: Forgot the players tested so far:
MX Video Player ~ Hit or miss on 1080p.
DICE ~ Hit mostly.
QVideo ~ Lots of misses.
VLC ~ When it worked it worked, I don't think its properly coded for 4.1 yet.
