I think we're already at some point there. I remeber back, like 99, 00, 01, 02....oh boy, everytime there was a new game with a new engine that required newer hardware. But since the advent of the next-gen consoles, this has somewhat tempered down. I can't remebmer (except Crysis maybe) a game now that has significantly higher system spect than games 2 or 3 years ago. You always read the same: "2,4 Ghz P4, 1-2 Gig RAM, 256MB DX9 Gfx card". Same as a few years ago, and it still holds for today. Also, there's UnrealTech, which will be used many many years still. If you can run GoW, you pretty much should be able to run any UE3 game for the foreseeable future.
