Just in from GameStop's Google+ page, Batman: Arkham Origins has been announced, scheduled for October 25th, 2013 and will be released for the Wii U, PS3, Xbox 360, PSVita, and 3DS. Here's hoping the portable versions are as good as the console ones and hoping this game is good PERIOD. Since it's got "Origins" on it I presume it's a prequel to the first two Arkham games, which I haven't played but have heard are good. No other information at this time since the only thing shown is the logo above on the various boxes, although a quote from the Wikipedia page reads:
The story takes place several years before Batman: Arkham Asylum and revolves around eight of the world's deadliest assassins that have gathered in Gotham City on Christmas Eve for one purpose: to kill Batman.Sounds like a good game, let's hope this works out.
