From my experience playing demos, i can never tell much of a difference between the demos and the final version of the game. Madden 10 demo looked the same graphics wise as the final build did.
Don't think the final build of 2k10 completely overhauled their graphics to make it where it doesn't look and feel like an arcade game when I play. Only thing that i can tell is great about the game is the overlays, and the announcing is by far better than the other games', which is pretty bad. I was just stating opinion and my impression. It's very hard to see much of anything i like after playing the show for a week now and then go to whatever that was.
