id Software technical guru John Carmack has told OPM UK anyone expecting to wait a long time for DOOM 4 will have a shorter wait than first thought.
Carmack told the mag the shooter shouldn’t take as long to get out the door, unlike RAGE, which was announced in 2007 at QuakeCon, and won’t be out until next year, producer Tim Willits told VG247 back in May.

Maybe this year?
