Update: Warner Bros have commented on the story, stating simply that: "Batman: Arkham Knight is due in 2015."
Original story: While Warner Bros currently has a general listing of "2015" for the release of Batman: Arkham Knight currently, Microsoft's U.S digital store has a more precise release date: February 24th next year.
That ties in close to what Batman's voice actor, Kevin Conroy, let slip recently. The store lists the game as retailing for $59.99.
It's not the first time that online retailers have let slip a release date before an official announcement, but equally they've also proven to be unconfirmed approximations. We've pinged Warner Bros for comment.
If this new date is the right one though, it means the Rocksteady sequel releases the same day as The Witcher 3: The Wild Hunt.
