Same thing happened to Half-Life 2. When they announced it, they showed screenshots and, later on, some clips from the game. The graphics looked awesome (and were). Only thing was, by the time Half-Life 2 finally came out, Doom3 (which has even better graphics) had already come out. Hopefully ESL4 will run on a non-top-of-the-line machine, though. I can't afford it! =)
