Australia’s Classification Board (similar to North America’s ESRB) has recently rated the title Sackboy’s Prehistoric Moves a G (General) rating. Sony’s never announced such a game. The classification lists LittleBigPlanet 2 developer Media Molecule and Tumble developer Supermassive Games as those behind the game.

Supermassive has released three games so far, two of which are for the PlayStation Move controller. Bundling that with the fact that the word ‘Move’ is in the title of this new game, we’re guessing that this’ll be a PlayStation Move-based title.

We’d contact Sony for comment, but honestly, we don’t expect anything greater than a “no comment,” so we’d rather not bother.

Thanks, Siliconera.
