Rumors that LittleBigPlanet is getting a PSP iteration have been around since April and were recently strengthened by a rumor found within the pages of the latest Electronic Gaming Monthly (EGM), so MTV's Multiplayer Blog asked Sony's John Koller about the rumors during a phone interview yesterday.

Koller's comments from the story:

"'LittleBigPlanet’ is so expansionary. I think the developer’s really concentrating on right now making sure that the launched product is everything it could be and can be. We’re watching the UGC [user generated content] and seeing how that’s playing out. But for the future, I think certainly, we’d look at a wide variety of opportunities. Whether that’s the PSP or not, I can’t really say. We certainly look at ‘LittleBigPlanet’ franchise as a going forward franchise for us, and that speaks to the PlayStation brand overall.”

Multiplayer also asked Koller about the possibility of Rock Band or Guitar Hero hitting the PSP, as well:

“It’s of huge interest to us. That’s something you’d really have to talk to the developers on that side [if] it’s going to happen or not. For us, we look at the music area as being critical for PSP and the social area of interest as well. PSP is a lot different than your traditional handheld product and music is the number two use on the PSP, behind gaming. So, the marrying of those two concepts is of huge interest to us, and if there’s that opportunity to launch a title like that or even a new title that utilizes music in some way, then obviously we’re very interested.”

Sounds like there may be something to these rumors. Stay tuned, we'll let you know if anything is announced.
