What is Sackboy's Prehistoric Moves?

A game called Sackboy's Prehistoric Moves looks to be in the works for PlayStation 3.

It was submitted to the Australian Classification Board for rating (spotted by Siliconera), which duly popped it onto its website for all to see.

Sackboy's Prehistoric Moves looks like a collaboration between LittleBigPlanet creator MediaMolecule and Supermassive, the developer behind Start the Party and Tumble.

Siliconera speculated that it's a PlayStation Move game, and we agree.

We'll ask Sony to shed some light.
