The Day After Tomorrow – The NEW PSP (no official name yet PSP 2 or PSP-4000) is said to hit retail this year before Christmas. While the news will hit this year’s E3, for now all the information regarding the PSP is a rumor.
From the screen alone, you can see the new PSP will feature a sliding touchscreen and the controls will be underneath. There will be a D-pad and two analog thumbsticks, for better Resistance: Retribution games! The screen looks magnificent, especially when closed. We understand the full specs and pricing will be unveiled at E3 in June.
