Answer:
Tim Willits, Lead Designer/Co-Owner/id Software
"Both id and Raven have been working hard to get the Xbox 360 version of the game out as well as the PC demo and the first QUAKE 4 SDK, and both teams are committed to continuing to support the QUAKE 4 mod community through www.iddevnet.com/quake4. There is already a ton of information available on the site, and we will continue to update that page with information, instruction, and any other news or initiatives that would interest QUAKE 4 mod makers."
