Good interview, not extremely nitty gritty - but great none the less.
I didn't hear this in the interview, maybe I missed it - but is Nick on the team for the next version or iteration of the XBOX (assuming that they have a team for this by now).
If so, perhaps a great follow up interview would be to find out what kind of tech they are looking into for the next version. I know it would probably be a 1000 foot overview not wanting to give to much away - but I am sure it would be very interesting none the less.
Again, assuming there will be another XBOX, I am curious if there will be a move back to Intel/AMD or if they will be sticking with the PowerPC.
