Batman: Arkham Asulym was a awesome game, and GRTV crowned it the Game of the Year 2009. We've known about the sequel being in development for a while now, but not much else. Now games mag Gameinformer has been kind enough to post a teaser for its next issue on its website, and lo and behold - it's Batman: Arkham City.
