Speaking to Eurogamer, Media Molecule boss Mark Healy has confirmed that a PSP version of LittleBigPlanet is under consideration.
"There's definitely scope for a PSP version," he said. "We've had discussions and talks, [but] nothing concrete at the moment."
Healy added: "It'd be great to make - for the people who are really into the Create side - some kind of companion products that allow you to create things while you're on the train.
"One thing that I'd love to add is the ability to create you're own music, for example, that you can import into the game. That seems like an obvious one to do and it'd be quite easy really."
More through there.
