This is basically what you’d expect from a Super Monkey Ball game cover. It has those cute monkeys you love, though this one seems to be showing more of a cut out art style. Reminds me of Kirby’s Epic Yarn sort of.
Even though Super Monkey Ball 3DS was one of the first shown and one of the first games to get gameplay footage online, it will not be a launch title for the hardware, at least in Japan. Nintendo put up their official line up of games and it excluded this title.
The title will actually launch in Japan on March 3rd, one week after the 3DS is out. Reason for this? No idea.
