In addition to first details on Gran Turismo 5, Polyphony Digital updated the official gran-turismo.com site with the latest on Gran Turuismo PSP. Much of the information in the update was already shared in interviews following the game's E3 announcement, but it's good to have it all in one place, and complete with screenshots.
