According to the CV of GTA V’s lead vehicle artist, the game is due for release this October. Said CV has now been amended, and the release date listing removed.
Since its unveiling late last year, all has been quiet on the Grand Theft Auto V front. What we know is that the game will be set (at least partially) in the Los Santos of Grand Theft Auto: San Andreas.
The release date makes sense in that Bioshock Infinite, another game from the Take-Two family, has been pushed make to next year. The rumour is that Infinite was pushed back to give GTA V some breathing space and to prevent the two from competing with each other.
