It would appear that Microsoft has let the bat out of the bag and pegged Rocksteady's Batman: Arkham Knight for February 24, 2015.
Earlier this month, Rocksteady announced that the game had slipped. “We just want to make the best experience we possibly can and we need more time to do that,” said Guy Perkins, game marketing manager told The Escapist.
The new date appears on the Microsoft Store, and at the time of writing has not been adjusted.
Batman: Arkham Knight is a new-gen exclusive, coming to Xbox One, PlayStation 4 and PC.
