Heads up Batman: Arkham Asylum fans, the sequel has been named and tentatively dated. The new game will be titled: Batman: Arkham City and will be available on Xbox 360, PlayStation 3 and PC. The website is live for the game, though at present it only features a short teaser trailer (above) and a register for updates link. Looks like Catwoman might be making a sexy entrance and of course the trailer features The Joker and Harley Quinn.
