Sony's Bend studio is currently working on Resistance: Retribution, coming to PSP in Spring 2009. After showing that title, a third-person shooter faithful to the first game, Sony's Jack Tretton casually dropped a few more:
LocoRoco 2, Patapon 2, NBA 09: Inside, Super Stardust Portable, Buzz! Master Quiz, Valkyria Chronicles and Midnight Club: Los Angeles Remix.
"We've always felt that the PSP was one of the keys to Sony owning the living room", Tretton said.
