As castell pointed out, I was actually making reference to the Xbox One there.
I did reference the original Xbox in a later post, and I mostly had the GPU in mind there. The NV2A is close to the GeForce3 in design, but it's still not quite the same chip that was available to consumers. It was kind of a stepping stone between the GF3 and GF4 and was designed to support some things that would later show up in DX9 while not truly being a DX9 GPU.
Close, but not quite the same as standard PC hardware, and that in-between generations nature of the hardware and APIs means that optimizing for it as a target platform is going to require extra time to get it working as well on "true" DX8.1 or DX9 hardware.
