Gran Turismo (PlayStation Portable game)

Gran Turismo 4 Mobile is a PlayStation Portable game developed by Polyphony Digital. The game was announced at the E3 2004 Sony press conference on May 11th, the same conference where Sony announced the PlayStation Portable.

It has since been delayed repeatedly and its completion has been pushed back until after Gran Turismo 5 Prologue is finished. The game is intended to be an exact port of the PlayStation 2 game, Gran Turismo 4. As of January 2008, no such game has been released in either Japan, North America, or Europe.
