Could Craftworld (LittleBigPlanet prototype) be in development?

LittleBigPlanet had some pretty humble beginnings. Media Molecule started with a 2D demo, then called Craftworld. Sony loved the approach they were taking with the game, and signed Media Molecule to develop what is now (our game of E3) LittleBigPlanet.

When speaking with Mark Healey, Newsweek's N'Gai Croal asked whether or not there were plans to ever continue working on Craftworld, either as a new PSN or PSP title. He stumbles a bit, almost revealing something: "There's--we're not allowed to talk about that, are we?" Unfortunately, the PlayStation publicist silenced him before he could go on further.

There's something happening with LittleBigPlanet. We just don't know what, yet. We'd be a little bit more demanding to find out more ... but we're too busy waiting for LittleBigPlanet to be finished.
