The game is set to be released in the land of the rising sun on October 14th. It comes with a change specifically for Japan: The characters representing Rich LeFevre and Juliet Lee will be replaced in favour of the Japanese Noboyuki "The Giant" Shirota and Hatsuyo "The Witch" Sugawara. Aside from this, the game looks exactly the same.
Still no word on when (Or if!) the game is being released in Europe!
