Well, that's a nice list. Good job Bethesda.
I'm especially glad about Shadows on grass available (PC), Improved visual transition when going underwater, Improved distance LOD transition for snowy landscapes.
Those were unexpected, and warmly welcomed

I'm personally not that happy about killmoves (but I still really appreciate the act that you guys are added new features, it's very nice; your gamejam stuff was awesome, please keep add!), but that's because I don't like forced third person as a 1st person player. I'll have to mod it out, if it's not optional...
There are some major things that still needs to be fixed. Seriously.
Extremely low sound for what it seems... a lot of stereo speaker users (which is really commen, so A LOT of people have the problem): http://www.gamesas.com/topic/1351097-so-when-will-bethesda-fix-the-low-sound-issue/
Also, mountain flicker / Z-fighting is something the majority of PC users experience. http://www.gamesas.com/topic/1336456-mountain-flicker-z-fighting/
And... the 64-hz issue/bug/whatever it is, really should be fixed. It's been in all your games since Oblivion I think. It's about time to fix it: http://www.gamesas.com/topic/1358196-bug-64-hz-again-plz-bethesda-fix/
Finally, shadows really should be improved: http://static.skyrim.nexusmods.com/downloads/images/148-1-1321243716.jpg
