id Software has announced that it will not be saying a single thing about Doom 4 until Rage is out the door.
Speaking to Ripten Creative Director Tim Willits said;
Were not going to give you guys so much as a f***ing screenshot untilRAGEis out the door
Technical Director John Carmack and CEO Todd Hollenshead also echoed these sentiments;
Dude If thats what Tim and John told you what do you think Im gonna say?!
So it would appear that we still have a few months worth of waiting before we finally get to hear anything official about Doom 4.
