Best trailer yet for the game, showing some good polish to it, better quality voice work.
The delay makes sense given what it would be up against in late 2012, and if the early 2013 date means more polish, it's a positive thing, plenty of other games to play until then.
On a side note, 0:57 "Where am I?" sounds like Bill Paxton, or at least someone who has a very similar voice...
