-you can start wars between hordes of militia??
-when you go to jail anymore your stats don't dissolve.. apparently they some can be reset?? hmm... and there is more than one kind of prison
-the story tracker actually tracks every thing.. even the little things such as dropping a plant or sword and also can differ how people treat you
-if you anger someone they aren't bound to what weapon if any they've been givin to begin with (in otherwords if they have a 1H mace that does 5 damage and theres a 1H or 2H sword that does 11 damage.. chances are that they'll be grabbing it before long)
-some enemies or civilians you attack will beg for their life(i know it's already been released that some will try to run)
-smart AI resulting in enemy ambushes?
-the ability to use tanning and smithing together to create different characteristics on weapons such as gold weapon/ wolf pelt handle??(even though i wouldn't want a gold weapon.. would be too soft :-p)
-not only can you do shield bashes.. but now also bow bashes if an enemy gets too close.
-Many factors will determine whether or not some guards will let you off some crimes (such as faction rep and such)
-when a crime is commited you can eliminate all witnesses and not be caught (also already been released)
-hand to hand combat may still be useful (and not only for tavern fights)

Sorry, but most of this is old news and has already been confirmed. You might wanna take the youtube link off, and thanks for trying to help though.

any of this new?

No, sorry. Only thing new to me was the gold weapon thing, which I already knew you could smith your own weapons, just didn't know you could make gold ones.
