I've got to say that the new combat system is definitely deeper and more challenging. I got smoked by Swen rather quickly in our match, in part because I was operating with a DOS EE mindset and that's a hindrance. You'll definitely need to re-train your thinking. Even more than the previous game, I feel like no two encounters will be the same.
The graphics looked fantastic to me and I didn't have any issues with the camera. I'm very much looking forward to it!
