What caught my eye is the graphics here. In Arkham Asylum all the clips where rendered using the Unreal engine and none were FMVs. This small clip looks like it is fully rendered for promotion only, but it could very well be from the game engine as well. Which if it is from the engine, HOLY FUCKING SHIT! They went leaps and bounds from Akrham Asylum to Arkham City in the visuals. Watch the clip in HD and say you would not be impressed if that is truly in game graphics.
I do have a feeling it is pre-rendered to help tease the first full trailer to be shown this Saturday, but one can hope. Right?
