Mario Kart: Arcade GP DX
According to translations provided by members of NeoGAF, other modes listed by Namco Bandai include a single-player Grand Prix mode, two-player Co-op, "Clone Battle" mode and a competitive mode, which will support up to four players.
It features Gliding and Under Water Driving from MK7, what seems to be double dash mechanics (according to the translation), and the same picture taking mechanic from other GP games, the courses look detailed. As of now, this is only coming to Japan. Once we here more news, it will probably have to do something with America, Europe, and Australia.
