I'm not a fan of how it looks in this first previews, but I'm interested to see the potential of this in future iterations. For example, I've seen a whitepaper of someone running something similar on top of GTA and make it look photorealistic. If this current implementation gets a couple more "papers down the line" this could possibly speed up development of games immensely and allow for a graphical fidelity that isn't feasible with current tech. But that's just potentially. Right now, I don't see what they've shown so far to be anywhere near releaseable.
