European publisher Zen United posted an update on Facebook today confirming that it is now in the submission process for Persona 4 Arena on the Xbox 360. The company also suggested that a May release is likely.
Zen United said: "An update for you today—and a positive one at that. We are now in submission for the Xbox 360 build of Persona 4 Arena. Though dependent on when it passes, of course—I think it’s realistic for me to say we’re looking at a May release."
