Little Big Planet ON PSP?

I am sure that you all have heard about Little Big Planet. Little Big Planet is one of the best PS3 exclusive games i have seen so far. In this game one can create a whole world by yourself in this game including the backgrounds, trees, obstacles and everything that one can imagine. This game has changed the way people used to look at games. And now Media Molecule is planning to bring LBP to PSP. The news are not confirmed but it is said that they are planning to bring out a PSP version. Rumors are that they will allow PSP users to import there own music in the game. If it comes out on PSP, i think it will help Sony to get ahead from its rival Nintendo DS.
