CEO of id Software Todd Hollenshead updated his .plan offering thanks to the many well-wishers on the occasion of DOOM 3 going gold, while providing some further details on what's happening with Mac and Linux editions of the game, a demo, and more:

Mac and Linux: Unfortunately I don't have dates for either of these. However, Linux binaries will be available very soon after the PC game hits store shelves. There are no plans for boxed Linux games. More remains to be done for the OSX version of DOOM 3 and that will take some time. We won't release the OSX version until it's just as polished as the PC version. The date for OSX DOOM 3 remains "when it's done", but I can confirm that it's definitely coming.

Demo: our priority was finishing the game first and now we are turning our attention to the demo. I don't have any information to share regarding any specific content, but I don't believe that we have ever disappointed in that regard in the past. We will release the demo as soon as it's done, but this probably won't happen until after the game has arrived on U.S. store shelves.

Last, but not least, the id Store: we will have copies of DOOM 3 available, but only after we get them. I'm sure that some of the hardcore game retailers will get them even before we do. Check our website for updates on this. We certainly appreciate everyone who has helped to make the id Store a huge success this year. By the way, more DOOM 3 T-Shirts just arrived, so those popular items are back in stock and will be available this week.

I understand that people have lots and lots of questions. We're working on pulling together some form of an official FAQ, but even though we're done we still have several responsibilities that are urgent as the game heads for retail. Please bear with us on this.

I know I owe you those preparation tips, but they will have to wait until tomorrow.
