This is only a rumor for now, but Gameblog.fr is reporting (industry sources...) that Rocksteady is working on a new Batman Arkham game to be shown at E3 this year: Batman Arkham Origins. This time, the story will apparently take place around the 50s or 60s, and other members of the Justice League would also appear in the game. The rumor says it will be a PS4-Nextbox title, but with a chance of seeing it on PS360 too.Here's the link to the original story (French only);Gameblog.fr's track record so far has been kinda hit and miss. Some of the rumors they posted ended up totally correct (I remember Child of Eden before the Kinect conference for instance) and sometimes not, so take it with a grain of Mont Saint-Michel salt.
