It's announced just now that Dengeki Bunko Fighting Climax will be released on PlayStation 3 and PlayStation Vita this Fall.
There's no other information but we expect it to have at least 12 playable characters and 18 supporters like in the arcade version.
The fighting game is a project to celebrate 20th anniversary of the light novel magazine Dengeki Bunko. It was released to the arcades on March 18. (And we have How to Play since mid-February)
