I've got my pre-order and am good to go! (PS3 version).

Some sites of interest:

• Official, badass, site: Rockstar Games: Grand Theft Auto IV
• World first review: GTA IV First Review (OXM UK) - NeoGAF
• Multiplayer previews: GTA IV online multiplayer previews today - NeoGAF
• GT page: Gametrailers.com - Grand Theft Auto IV: Reviews, Trailers, and Interviews

And no, Dangar^, this isn't an advertisement, nor does it seem like one...
