The TechReport crew have a write-up summarizing the keynote from the Carmack down at Qcon this year.

"He was back in typical form, delivering his speech without notes, seemingly off the top of his head. The speech was still crystal clear and reasonably well organized, as one might expect from a renowned programmer. His topics included next-generation game consoles, the problems with physics acceleration, and what he'd like to see in future graphics hardware."
