Rumors are circulating that GT3 is coming soon for the PC. But they're wrong.
"We've seen a couple of posts on this already so we thought we'd clear things up a bit. A short time ago, in an interview Kazunori Yamauchi stated that he would like to bring Gran Turismo 3 to the PC to "reach a higher audience." His comments weren't meant to imply that the game is coming to PC -- just that it would have a sizable audience if it did. Our contacts at Sony have categorically denied that there's any truth to the rumor so it looks like, for now, PC gamers will have to get their racing fix elsewhere."
