GameSpy has word from WBIE at Comic-Con that Batman and Bane will team up a series of missions in Batman: Arkham City, the upcoming Arkham Asylum sequel (presumably these won't be back-breaking). They also note a tidbit apparently revealed by New Zealand-based MightyApe that different versions of the Batman will be offered as retailer-specific bonuses, offering an image depicting Bats from Batman Beyond, The Dark Knight Returns, Batman Earth One, 1970s comics, Batman The Animated Series, and Rocksteady's Batman (sorry, there doesn't seem to be a batusi dancing Adam West version).
