Rockstar Games has announced via the medium of Twitter that:
"Grand Theft Auto: Chinatown Wars coming October 20th for PSP. First screens and more coming soon."
Will it still be on disc for my old school PSP 3000?
"Yes, it will be available as both a digital download (via Playstation Network) and a retail UMD."
Well, hurrah! We've got a look at it coming up.
