Rockstar have just announced that the previously Nintendo DS-exclusive Grand Theft Auto: Chinatown Wars is coming to the PSP. According to the press release, the game will be available at both retail and digitally via the PlayStation Store. The release notes that the game will “take full advantage of the power of the PSP”, so it’s safe to assume the visuals will be cranked up a notch. It’s possible that the move is the result of the game’s disappointing sales on Nintendo’s portable. No release date for the PSP version has been announced.
