Batman has been the sleeper character of this gen, nobody expected that quality. We have had a lot of Batman crap games along the years, so, Rocksteady Games shocked everybody with Arkham Asylum. Yes, it’s not like the comic, but it’s terrific.
The Dark Knight could return this year in a new adventure. A Warner Bros insider stated that his company is developing a new Batman game for this year, inside Arkham franchise. VG24/7 claim Rocksteady aren’t working in the title. They have their own sources.
Arkham City released late 2011, that’s plausible to have a new game two years after, without Rocksteady? I don’t think so.
