That was actually far from rushed; all the animations, all the textures, the gameplay, the little details were all there and well polished. It was a well-crafted demo that looked like it was from the actual game polished for a presentation. I really wouldn't expect the game to change that much in a year, especially if they are going to make that 60fps framerate. Things will change no doubt, for both better and worse, but I don't think there will be anything dramatic happening with the graphics. Certainly nothing like adopting full PBR, but with more polish I can definitely see it ending up looking a bit better and I think there will be other environments that will definitely look a lot better in comparison.
