Anyone remember the gamecube's tech demos? No? How about the PS2's? Anyone remember what they were showing us the N64 was going to be capable of? Tech demos don't mean anything one way or the other. For one thing, they're usually only a short demo, so storage space isn't as much of a concern. For another, they're created with ideal conditions in mind. This means that if something doesn't look quite right, they can go back and tweak it over and over again until it does. You just don't have the same concerns with a tech demo that you do with a full game. You're all making a big fuss over nothing. Wait for the actual games, then we'll have an idea of how to gauge things.
