LittleBigPlanet developer Media Molecule, over the weekend, updated the "games" portion of their website. In doing so, the studio revealed a new teaser for a "mysterious" upcoming game.
The new project is listed as "?", and the dedicated page contains a YouTube video of Toyah Willcox singing "It's a Mystery." Attempting to scour the source code for any hints, Media Molecule has cleverly teased the keywords: "what are we doing at the moment, exactly, mystery, new game, how awesome will it be?, who knows."
