WASD have a video up of the QuakeCon Doom movie panel, which shows a rough cut of the full trailer due in about 3 weeks. It includes a fair amount of FPS POV footage and looks pretty immersive IMO -- hello pinky! Just after the 26min mark about three minutes of the continous FPS POV scene is shown as well. The panel also discuss the monster design and production.
I just got an email that says Universal Studios may change the name of DooM: The Movie to ATi : The R520.
But it's still a rumor, therefore don't quote me on that...
