On the Xbox News website, the following image was posted to showcase a feature in which makes it easier to discover games on Xbox in a preferred language. Although, those of us who are eagle eyed, spotted a X|S badge on the cover of Batman: Arkham Knight, which suggests the game will be getting a next gen version! Although it is important to point out that this could just be a badge suggesting that the game performs best on those consoles, or could simply just be an error from the person who created this image. Although as its on an official Xbox website, this is unlikely.
No further details have been released specifiying whether this is a Xbox exclusive or not, but we will be sure to update on this as it moves along.
