Very cool. Some of the most beautiful and realistic lighting I've seen in a game.
However, the game I'm probably most excited about graphic-wise is id Software's Rage, which doesn't only feature absolutely breath taking outdoor environments, but also has an engine that's unconstrained by texture limits and allows for a complete malleability of the environment by the artists. So the level and detail of design is outstanding (besides, I'm partial to single-player open world games that mix genres).
