For a lot of people, video cards will have improved enough in that time frame, that they will just buy a new card.
You mean for people that play games (mostly under Windows) and need to buy latest and greatest every one or two years? For the rest of us, I don't see any reason why we would fork $100 every couple of years for new video cards, when the old ones work just fine (and more than fast enough, thanks for asking).
