Portable LittleBigPlanet feels just like LittleBigPlanet on the PlayStation 3. A demo level had Sackboy collecting score bubbles and dragging boxes to make platforms.

The system has a pop up 3.8″ screen with the buttons underneath it, similar to a Sidekick. It’s 43% lighter than the PSP-3000, has 16GB of flash memory, bluetooth support, and no UMD drive.

Ars Technica’s mysterious mole claims the UMD-less PSP Go! and a slim PlayStation 3 will be in stores later this year. While both products are remain rumors, Ars Technica procured early information about the Resident Evil 5 Xbox 360 bundle and disc-less Patapon 2.

The never ending rumors of a disc-less PSP continue to spark with 1up reporting on a device called the PSP Go! The new system is said to have a 8 or 16GB of flash memory and a slideable screen.
