still a rather doubtful premise. Only problems would arise, in that case, from specific old generation nVidia tweaks. This would be a problem only for purely console style built games i.e. extremely tailor made to the platform might have problems, but then most console games nowadays, my impression is, are multi-platform regardless.
They were good enough to run on Xbox, they'll be good enough for Xbox 2, especially considering the case that they were already ported to vastly alien platforms in the PS2 and the GameCube
If the only relevant difference is an upgraded video card, rejoice. xbox has the ultimate backward compatibility of all the consoles. I always knew the Xbox line was the answer; that the path of the future lay in the convergence with computers.
Puahahahahaha
