No Official Doom Shots
Of course this doesn't rule out that other sources might come up with videos or images. The only image that surfaced so far, is this one.A quick email from Stomped to id's CEO Todd Hollenshead has him stating that there will be no screenshots or video released by id of what was shown of the Doom 3 engine during the keynote speech
Update: The first footage has finally appeared, at CNET Tech News. Click the "Jobs introduces "amazing" Geforce 3" link (on the right side). Go now!
For those of you who can't quite stream that video, I took some shots. Be warned, these are low res and still images don't do the effects justice. View the video when you can. It is REALLY impressive.
