Hot on the heels of the PSP Go announcement, Sony also tells us at E3 that Gran Turismo may finally see release on the system. They say that even though the game will be on the tiny system, it will be packed with content: 800 cars to race around on 35 tracks with multiple variations that actually allow for 60 different race route. In singleplayer, you'll be able to run singleplayer time trials, and there will also be a mode to help your driving improve. Multiplayer will bring ad hoc four player racing as well as the ability to trade cars back and forth with your friends.
The game will release on October 1, right alongside the new PSP system.
