It looked like Grand Theft Auto V was imminent on PC (an announcement at least), but so far no official word has come from Rockstar, just retailer listings and whispers of impending in-store promotions.
You can add more rumours to the mill after TechieNews highlighted several retail listings in a recent post. Apparently Portuguese retailer Worten briefly listed a PS4 pre-order for the game (which we can't find now), and - according to TechieNews - SuperGamer were also pointing towards an Xbox One version of the game coming in June alongside a PS4 release.
Basically, the links featured in the news piece in question have now been taken down (except this one - which points to Steam codes for the still unannounced PC version), so take these reports with a huge pinch of salt. It seems as though Rockstar are content to keep us waiting for now, for both the PC version of the game, and for a potential new-gen versions of last year's best selling title.
