An IMdb listing for the Batman: Arkham Asylum 2 reveals that trusty sidekick Robin will be appearing alongside the dark knight. Arkham 2 was revealed at the Spike TV awards at the end of last year but ever since, we’ve literally heard nothing of the game or it’s progress. The casting lists Vincent Martella as Robin (you might know him as Greg from Everybody Hates Chris) and returning voice actors Kevin Conroy as Batman, Mark Hamill as Joker and Arleen Sorkin as Harley Quinn. Let’s hope we hear something about Arkham Asylum 2 this week at GDC 2010.
