Let's talk facts. Every single numbered Grand Theft Auto game has been available on the PC. But that hasn't stopped people freaking out over the fact that the latest game in the series, Grand Theft Auto V, has yet to be announced for the platform.
In some ways, you can understand their concern. The PC is stronger than it has been in over a decade, thanks to services like Steam, so Rockstar keeping silent makes it look like they're ignoring easy money. There's also the fact that the company's last open-world smash, Red Dead Redemption, never made it to the PC.
On the other side of the argument, though, is the fact Grand Theft Auto IV was released in April 2008, and it took until August 2008 for a PC version to even be announced.
That and one of the world's biggest PC companies is now even acting like, eh, whatever, of course it's coming to PC.
Speaking with PC Gamer, Intel's Chris R. Silva has said "...with Grand Theft Auto I don't think it'll be console exclusive very long. But that's what happens when you have a brand new launch with two companies that have lots of money trying to make sure they have content."
In case he didn't make his theory clear enough, he then adds "Somebody paid a lot of money to make sure that title was exclusive."
I'm not sure it's something that drastic keeping the game off the PC - it's likely just the customary delay - but hey, until we know the truth of the matter, all possibilities are on the table.
