Sony Computer Entertainment have accidentally leaked some secret documents pertaining to future plans, and as well as revealing that games are heading for the PS3, the papers also hint at some of Sega's future plans.

Apparently, the Japanese gaming giant is hard at work on a new superhero game, some two-and-a-half years in the works, starring Nordic legend Thor.

The documents reveal that the game is clearly quite far-advanced, having requested code on the game from Sega.

A new Thor-based film is said to be on the way, the game apparently earmarked for release alongside this cinematic offering come 2011. Thanks MTV.
