http://www.doom3.com/ has just got fully live, no more static coming soon crap.
BTW (1), in their media section they have a clip of intro music to the game. The first thing I thought when I heard it was, "SHIT! That's Tool!!!" then I remembered the rumour about Tool and Reznor teaming up for music, that rumour just got confirmed! BTW (2), Reznor's sound design is incredible, having played the Alpha and having shit scared out of me when the neo-Pinky demon burst through the pipes... God that fucked me up.
EDIT: Shizzam! Just found out that Reznor pulled out of Doom 3 in 2003... what the shit man, I hope they didn't throw his stuff out!!!
