Doom III?

John Carmack's plan (of id software) reflects an interesting update:

"We are working on a new DOOM game, focusing on the single player game experience, and using brand new technology in almost every aspect of it. That is all we are prepared to
say about the game for quite some time, so don't push for interviews. We will talk about it when things are actually built, to avoid giving misleading comments."

Along with some news about internal unrest at the company.
