A bit more surprising is Persona 4 The Ultimate In Mayonaka Arena. Atlus is teaming up with Arc System Works for a 2D fighter that will be released first for arcades in Spring 2012, then for PS3 and Xbox 360 in Summer 2012. The game is being developed by the BlazBlue team.
The Ultimate in Mayonaka Arena has a new story that takes place two yeas after the events of Persona 4. Characters from Persona 4 and Persona 3 will feature in the game.
