For the last few years, those clips have been of "Doom 3," which is nearing completion after a four-year development cycle. This year, most fans were hoping to get their first glimpse of "Quake 4," which is being developed (under id's supervision) by Raven Software. Unfortunately, they're going to have to keep waiting. id CEO Todd Hollenshead said there are no plans to show the game at this year's QuakeCon.

"We've been happy with what they've done, but it's too early to show," added id's lead designer Tim Willits.
