A little bit of CG. A little bit of direct feed gameplay footage. A whole lot of monkeys in balls.
Sega featured a new Japanese trailer for Super Monkey Ball: Step and Roll on their Tokyo Game Show media DVD. The newest trailer actually combines footage from the first CG trailer along with gameplay footage that shows off some of the Balance Board controlled stages.
Super Monkey Ball: Step and Roll is slated for an early 2010 release.
