"We're working with Nvidia to develop a graphics chip which is a step beyond the NV20, it's called the NV2A. In early design discussions, we did loosely refer to it as an 'NV25', but decided to change it to NV2A to avoid, not incite confusion. it's a custom chip which is designed especially for the Xbox and some very specific requirements for the console that makes it a non-candidate for a pc card and will be faster than the NV20."
