Well...The title looks to be deliver on the promise of what Kinect can deliver...Killer Instinct Kinect...ooohhh aaaahh. Lag might be a problem, but Microsoft seems to be throwing alot of effort to improving the software coding almost weekly, and also I heard an interview with the guys from Harmonix, about how they developed there own skeletal modeling for kinect, which for there purposes what more accurate and responsive then M$ solution. So, I think by the second wave of Kinect games, lag is going to be almost a nonfactor.
