I hope for your sake it does too. The last MGS game I played was on PS2 and I loved it. I spent hours playing MGS on the PS1. At least it really is an exclusive on PS3. I think the days of console exclusives are numbered though.
Muhwahahahahaha! Another convert to the cult of PS3. My PSN ID is SEB_Dude when you get around to signing up for it, though the only multiplayer game I have at the moment is GTA IV. It'll probably be awhile before I can pick up MGS4 as we're spending quite a bit of money on my kid's graduation celebrations and moving into new digs.
