If graphics meant that a game was going to be high quality Lair would have been the game of the year ...
The Killzone series has been overhyped since it was first announced, always sold as a "Halo Killer" that was going to take the world by storm. In the end the first Killzone was a mediocre game that has no evidence (except for a forum post) that the game ever sold more than a million copies.
The one thing that makes me doubt that Killzone 2 will live up to the hype more than anything else is that this game has been under development for a very long time and very little has ever been truely displayed; it was claimed that Killzone 2 was well under development at E3 2005, and almost 3 years later it hasn't been widely demonstrated in a playable form. I have seen this type of behavior from a publisher before when they have allowed an underqualified development team to produce a project that is beyond their means to manage, and it doesn't end well ...
