It was a pretty sure bet that Sony was going to be announcing a revised PSP at their E3 press conference on Wednesday (NZ time), but a video leaked onto the internet appears to have stolen their thunder.

The video, an episode of a PlayStation-focused show called Qore, prematurely reveals details of Sony's new handheld, called the PSP Go. The video features an interview with John Koller, director of hardware marketing at Sony Computer Entertainment America.

The PSP Go will be sold alongside the existing PSP-3000 as a more portable version. It features a smaller, sliding form factor, the screen size has been reduced to 3.8" (from 4.3"), it's "43% lighter", has Bluetooth support and packs 16GB of flash memory plus a MemoryStick Micro slot. The UMD drive has been done away with entirely in favour of "all digital content".

"I think that's going to be something that a lot of consumers really like," said Koller. "You can just download straight to a hard drive."

Also mentioned are some of the games in development for PSP, including a Gran Turismo title "to be announced at E3", LittleBigPlanet, Jak & Daxter, "and there's even a new Metal Gear Solid coming."

Main differences between PSP Go and PSP-3000

  • Onboard flash memory (16GB)
  • Bluetooth support
  • Smaller form factor

Sony has apparently shied away from making significant changes to the platform (no touch screen or second thumbstick, for example), meaning all games should be compatible with both devices.

"You've got the most immersive games on the PSP platform anyway, now you've got a smaller unit to do it with," Koller said. "It won't replace the PSP-3000, we're going to keep them both on the market."

No mention is made in the video of a release date or pricing, but it's possible more details will be announced at E3.
