Due this fall, the PSP Go does away with the physical UMD drive and instead relies on downloaded digital content. It packs 16GB of internal flash memory, a 3.8" screen, Bluetooth support, and is 43% lighter than the last version of the PSP, the PSP-3000. Owners will also be able to expand storage capacity with a Memory Stick Micro.

Alongside word of the new hardware design, the long-awaited PSP edition of Gran Turismo and a new Metal Gear Solid title for the PSP were mentioned, with more on both expected to emerge during next week's E3 conference.

The PSP Go will not replace the existing PSP hardware already on store shelves, Sony hardware director John Koller asserted, but will instead complement it. Sony will continue to sell games on UMD discs alongside the downloadable versions, with more disc-based PSP games are coming to the online PlayStation Store as downloads.

How, or even if, existing PSP owners will be able to download their existing UMD-based games to the PSP Go without repurchasing them was not discussed.

As with the existing PSP, the Go will be able to stream PlayStation 3 content through Remote Play functionality. Koller also noted that Go will be able to download movies and television shows that have been purchased or rented through the online PS Store.
