I did a search for Carmack and it came up empty... so don't rake me if old.

Next Generation Online has culled a few John Carmack quotes from PC Gamer UK, including word that the Xbox 360 is going to be their primary development platform.
Quote:
"The Xbox 360 will probably will be id's primary development platform. As it is right now, we would get the game up on the 360. When I would do major hack-and-slash architectural changes it was back on the PC, but its looking like the Xbox 360 will be our target. All of our tools are on the PC, and were maintaining the game running on the PC, but probably all of our gameplay development and testing will be done on the Xbox 360. Its a really sweet development system."
