French gaming site GameBlog.fr is reporting that its sources say the next entry in Rocksteady's Batman: Arkham series will be Batman: Arkman Origins.
According to the rumours the game will be revealed at E3 this year and will feature members of the Justice League. Interestingly the report also suggests the game will be set in the 1950s and 1960s. GameBlog's sources suggest the title will be a PlayStation 4 and Xbox 720 game which seems likely irrespective of the other rumours about Arkham Origins. It is possible the game will see a cross-gen release on PS3 and Xbox 360.
It is believed that Superman and the Green Lantern are among the Justice League heroes who will star in the game.
Last year Arkham Aslyum and Arkham City writer Paul Dini announced that he would not be returning to pen future games in Rocksteady's franchise. Earlier this year 15 Batman Arkham web domains were registered including some for Arkham Origins and Arkham Universe.
