I'll grant you that the graphics aren't improved conserably, but I don't know how much of that is focus on other things and how much is limitations of the systems.
You're gonna have to face it man, this year was spent implemeting online play for the PS2 and they threw in some extra fluff (like more teams and mascots, entrances, cannons, etc) so the offline crew didn't have the same exact game.
But the vid's don't show alot of the new nuances added like the rollout cam and such, so there is no telling how different it actually plays. E3 should have some better vids come out of it. Overall....this is a fluff vid that could have been shot last year and looked the same. It's all a part of the Pre-E3 game.
