Batman Arkham HD Collection - remastered versions of Arkham Asylum and Arkham City plus all DLC - will be revealed today ahead of a June 10 release date on PS4 and Xbox One, according to an alleged GameStop document leaked to Eurogamer.
According to the document, the two games will feature "updated visuals optimised for PS4 and Xbox One", though the more recent Batman: Arkham Origins won't be included.
We heard the same thing last year.
The game has also popped up on PEGI, listing Batman: Return to Arkham - Arkham Asylum on PS4 with an April 19 release date. The date, says Eurogamer, is actually the date of pre-orders going live.
Expect to hear more info later today.
