This shot doesn't really take advantage of the kind of shading power that will be available next gen though..it's really SM2.0 stuff (AFAIK, the team only started working with 6800s, and SM3.0, after this prototype was shown off). SM3.0 opens up some interesting possibilities for scenes like this where you have lots of similar geometry, specifically in terms of introducing variation. I'd expect, for example, that at the very least the men in these armies would all no longer look the exact same, as here. When you introduce variation, there should be a big perceived visual improvement.
