jellybean 4.2,
99% of the cool/important stuff already available right now in 4.1.2 cm10/aokp/pa/samsung JB.
(new camera, photo sphere, new clock, gesture keyboard, new google now, new swipable gmail)

whats missing are the very minor/useless stuff.
~quick settings panel (which is totally useless, never once use it at all, cm10 toggles are way better)
~minor extra animation in recent app list.
~different way of telling you permissions when install apps in play store (nothing major, no one reads it anyway)
~multi user (only available on tablet, useless on tablet too due to nexus tablet having limited storage)
~day dream, if you have a dock, it activate screen saver. (words cant describe how stupid/useless this feature is)
~lock screen widget (which is quite useless imo, due to limited widgets. i mean just unlock and get to your full widgets in homescreen isnt that better? )
~miracast, somekind of wireless HDMI thing (i think most of us dont have TV that support it anyway)

but anyhow, its nice developers still taking care of s2.
