Well, those pic\'s are from the developer "Inevitable" who are also developing for the PS2. We will hopefully see both PS2 AND Xbox screens and then we will really see.
I have no doubt the Xbox\'s graphics will be sa-weet, but I do have some reservations about the Xbox having pixel shading and all that. If it\'s a standard for Nvida I guess it will, but if it costs more to integrate maybe it won\'t. I have no clue. It would be nice to get conformation on the exact preformance of the GS that will be in the Xbox, and not just Nvida\'s specs alone, especially since according to the official xbox site the GS is said to be a "joint" Nvidia/MS chip. That could mean certain specs or features are altered or even omitted to keep costs down.
