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.
Also Rockstar Games recently posted a leeds job listing that hinted at a GTA V PC port so maybe it's not out of the question yet?
The job posting before it was deleted: "Rockstar Leeds are currently looking for a talented graphics programmer to help bring our latest titles to the PC platform. Working together with the other Rockstar studios, you will be responsible for maintaining the studio’s uncompromising quality bar, delivering the highest quality PC experience possible."
