In its quarterly earnings call, Activision announced that Doom 3 won't be out until early 2004, but reminded that "as you know, id decides when it ships, not Activision." According to Activision, they have it "penciled" on their calendars for fiscal Q4 (Jan-March) 2004. Many people thought Doom3 would be released by Christmas of this year so that it would have a better chance competing with Half-Life2.
