This time Rocksteady is back for the brand new Batman game that is looking to be out possibly around October.
http://www.youtube.com/watch?v=wsf78BS9VE0It's been said and as the trailer shows, that the Batmobile will be drivable, meaning the city could be alot larger this time. It also looks to be the last Batman game, at least for Arkham related Batman, as I'm guessing Rocksteady wants to move on to different IP's. It is also possible that it could just be for this version of Batman and they might move on to other styles of Batman or heroes. I'd be all over them doing a Justice League game lol
The video confirms at least a few villains like Scarecrow, Two-Face, Penguin, and Harley. If there is Harley, there is definitely the Joker, but who else will show up is anyones guess right now.
