Major Nelson points out this article on Ars Technica that delves into the innards of the Xenon processor which will power the XBox 360. The article talks mainly about procedural synthesis, which is essentially using the CPU to generate vertex data for the GPU in real-time based on higher-level descriptions of objects that take up less memory and take less time and bandwidth to move from main memory into the CPU. Perhaps this could be one reason for the recent lack of posts in Mat Noguchi’s blog, and Bungie are working their tools programmer hard to take full advantage of this feature for Halo 3?
