A good interview with Tim Sweeney on the development of the future
Unreal 3 engine:

He says "...we're going to make a game that brings today's GeForce
FX's and Radeon 9700+'s to their knees at 640x480! :-) We are
targetting next-generation consoles and the kinds of PC's that will be
typical on the market in 2006, and today's high end graphics cards are
going to be somewhat low end then, similar to a GeForce4MX or a Radeon
7500 for today's games".

I also like the part where he says he wishes the Intel integrated
graphics chip would just "go away."
