If this isn't true then Rockstar had better say so because a lot of game sites have picked up on it and are running stories about it. I would say it's true he seems pretty sure about what he's saying.

Microsoft Entertainment boss Don Mattrick has given everyone the impression that online multiplayer in Grand Theft Auto IV will be exclusive to Xbox 360.

His comments came during a a podcast with MS community face Major "Larry Hryb" Nelson about the line-up of games for 2008 and what makes it special.

"[GTA IV] is an amazing piece of software and I'm really excited with its downloadable content and online multiplayer support. Again, that's something that's unique to 360," said Mattrick.

"We think consumers are going to love that and it's going to create, what I would describe again as the premium experience on our platform."

Update: Don Mattrick gave supporting evidence to msnbc in December last year. This time it is a little clearer.

"We're excited about Grand Theft Auto [IV], not only because it's a great title, but there's multi-play and downloadable content that consumers will only be able to get on 360," Mattrick told msbnc

"That's a huge win. Arguably that title has the potential to be the Halo equivalent in calendar year 2008 in terms of number-one title revenue unit."

360 version ftw :)

Well there goes my only reason to get a 360. Hopefully the requirements arent too high.bonethug1213

If that was your only reason to get a 360 then I feel that you probably wouldn't have ever bought one anyway.Lemmings don't care if this goes to PC, it's not a system seller, it's like Jade empire going to PC, who gives a ****

Plus this has been on the cards since EA bought Bioware, it was only a matter of time.
