@ HappyNoodle,
That comparison picture needs to be updated. I think there's a newer one that was made with the build shown at Sony's Playstation day a while back. It's better in areas that the E3 2007 build was really lacking at the time (like textures for example).
*edit* here's one, but I don't know if there were others.
