Nvidia at the Pulpit3Dpulpit has an interview up with Brian Burke of NVIDIA. The interview focuses on his opinions of things such as FSAA and more (including some mentions of the Xbox):
Is the X-BOX development part of your job spec in so far as the PR for it goes? Is the X-BOX project the main priority for NVIDIA at the moment?
Look for Microsoft to handle almost all of the public relations and marketing of Xbox, NVIDIA will do what it can to help out; but at the end of the day this is a Microsoft product.
