Looks like the Xbox 2 is starting to come together - almost. ATI is apparently now rolling out the R500 Shader Model 3.0 part that will be the console's new graphics chip. However, delays have been caused by hardware incompatibilities between the Xbox 2 hardware and Xbox 1. Other problems facing the platform are that a number of games targeted for the console have all sorts of Nvidia specific stuff programmed in, which is obviously causing problems with the ATI hardware.
