the only real new thing is a description of a very interesting sounding quest from the "dark brotherhood". you have to get into a house and murder 7 people (poison them, stab them or other stuff). the whole description sounds like its in a "agatha christie" detective storie style: 8 people (including you) have been invited to a manor and have to stay there for the night. over the night, they get murdered one after the othe. of course, no one knows whos the assassin (you). well that depends on you actually

i dont know about you, but i think this one sounds really interesting.
on the dvd there are only some longer clips of footage we can already see in the trailer. once again: the graphics of oblivion are outstanding ... trust me... it looks simply amazing!! the woods move to the wind and stuff, and everything looks so real.
i had my doubts about some of the animations, but from what i can see in the trailer, they have improved A LOT. monsters move realistic and npcs dont walk like funny muppets anymore.
