is there a release date for pc?
Weird that no one answered this. No there isn't. But don't worry too much. Most GTA games that come out as "console exclusives" come out on PC in about half a year to just over a year. So obviously, its a big wait, but itll definitely be worth it in the end.
If you dont need the upgrades for anything else, then id recommend you wait out until GTA V actually gets announced or comes out for PC>
There is some proof in some of the codes of the games that GTA V will come out on PC and PS4. But then again, it could just be made up to try and attract attention to the website!
