I also remember another interview or speech where he said he still had a "be all end all Quake" to develop, where he would put max emphasis on geeky stuck like device responsiveness and so on.

I think the guy will eventually come back to id some day to fix this fucking mess and make an actual good, new Quake. Until that day, Quake 3 was the last good MP competitive game that reached mainstream status, not accenting this cold hard fact is coping.
