In the New Adventures trailer I would agree with everyone saying that there is a graphical downgrade, but the latest build is the live letter build of the game, which you can "hardly" notice any differences, ( only for the extreme picky people). They aren't even done optimizing yet, so its going to look a lot better than what it already is.

As I said before in other threads: "Doom and Gloom must be the new fab these days"
