Well, they're certainly better but the differences are only instantly noticeable to those who know what to look for. As someone else put it, there's a huge difference in impact between everything suddenly having real shadows and everything suddenly having sub-surface scattering. They're both huge leaps but this gen's is WAY less obvious. It's something that will probably be way more noticeable when we can actually see the games being played and see everything being processed.
This generation's (and future generation's) improvements will more than likely be about being able to do more and more things at one time than any huge change to how the graphics actually work. Which makes me excited, not disappointed.
