Persona 4 Arena, Atlus and Arc System Works' confrontational extension of the Persona universe, was announced two weeks ago with a rather vague "summer" release window for its North American launch on the Xbox 360 and PS3. Apparently that meant "the tail end of summer," as Atlus has specified a slightly more specific August, 2012 window on the PlayStation Blog.
When it does launch, the game will include the prerequisite Online mode, as well as a console-only Story mode, which Atlus is attempting to populate with the English voice actors used in Persona 3 and Persona 4. In situations where English actors aren't available, we always recommend using Scottish or Welsh actors as a substitute. Their geological proximity to England often gives them a familiarity with local dialects that can be useful when replicating an accent.
