told CVG that a PSP version of
Little Big Planet is in the works. It's not hard to see the benefit of a portable version of the game as you could play and design levels on your PSP while you're on the road or even surf other people's maps to upload when you get back to your PS3. It might even be possible to create new game assets or even work on customizing your sock puppets as well. I'm hope this pans out as I have a feeling I'm going to be spending a ton of time with the game when it hits this Fall.
