A listing for Batman: Arkham Knight appeared on the GAME retailer site. While no longer available to view, the game was listed for PS4, Xbox One and PC. A Google search limited to GAME's site shows the listing existed in some capacity before being pulled by the retailer.

Update: Game Informer revealed that Batman: Arkham Knight will be the cover of its April magazine. The game will be the final one in the Arkham series from Rocksteady, and is set after the events of Batman: Arkham City. The game will feature the Batmobile and a new area of Gotham City reportedly "far larger" than that of Arkham City. Batman will spend his time in the game hunting down familiar foes: Scarecrow, Two-Face, Penguin and Harley Quinn in particular. [Image: WBIE]
