Short answer no. But then again there will be a lot more on screen action going on with GoW III than Uncharted. I played the GoW III demo and while it looked great it defiantly is no Uncharted 2. It would be very hard to make it look better than Uncharted just because of the amount of sheer action going on at any given point in GoW.
On another note GoW III was the best and worst 10 min tease I've ever witnessed. (Dante's Inferno's Cut-scenes we pretty fantastic though imo)
FootballFan - "GT has never been bigger than Halo. Now do a comparison between the two attach ratios and watch GT get stomped by Halo. Reach will sell 5 million more than GT5. Quote me on it."
