Newly announced today is Persona 4: The Ultimate in Mayonaka, an HD fighter based on the Persona 4 game, characters, and story. The BlazBlue team at Arc System Works is handling this project, with direct involvement from the Persona team. The game is due for release in arcades (in Japan, obviously) in Spring of 2012, with Xbox 360 and Playstation 3 versions to follow.
