The petition calling on Rockstar Games to release GTA V on the PC has surpassed 200,000 signatures.
Rockstar Games co-founder Dan Houser has stated in the past that a PC version is "up for consideration," but hasn't mentioned anything about it since. If Rockstar doesn't change their mind, we will have to wait for up to eight months after the game is released on the consoles to play the PC version.

Oh the things I would do for GTA V on PC and PS4... sigh.
