LittleBigPlanet Studio Teases New Game, Possibly PS4 Title

Media Molecule, the studio responsible for LittleBigPlanet, has revealed that they're working on an unannounced game. They've uploaded a video to their website to begin the tease.
The new game is simply listed as "?" on their website. The page for this secret game has the music video for the 1981 song "It's A Mystery" by Toyah, below. So yeah, not very informative.

The timing of Media Molecule's tease seems curious. On February 20th, Sony plans to hold a special event called "See The Future." They're expected to announce the PlayStation 4 at this event. Maybe MM will announce a launch title for this console?

MM is also currently developing Tearaway for the PS Vita. They plan to release that game later this year.
