One thing that bothered me about "Clang" from the start is that I was never really convinced that a Kinect-like system couldn't do it better. Per Clang's FAQ, their position was that the Kinect had too much latency. The first generation Kinect had a latency of 90 ms and the second generation had a latency of 60 ms. A bad, but not atypical display has a lag of 3-4 frames, so the newer Kinect roughly doubles the lag (or more) of a typical gaming system. Not so good! However, for how long will that remain the case? Arguably, a better approach would be to work on a low-latency form of Kinect. First, this would provide richer input that includes the players body position in addition to his blade, which could make hit detection more realistic. Second, a Kinect system with lower lag would have more general utility than just playing sword games. e.g. Unarmed combat would be an option too. Additionally, authoring sword combat software for Kinect-like systems would allow you to release something imperfect on existing hardware. It's great to shoot for the stars, but picking off some low-hanging fruit first can help you get there! Clang controllers used a few methods to give users feedback about hits. Obviously, there was no way to make the controller stop in mid air as though you'd hit a concrete pillar with your sword. However, it could use rumble packs in concert with audio cues to simulate glancing contact with an opponents sword or light cuts to his body. There's no reason a Kinect-compatible stick couldn't include the same sort of feedback. So what's the next realistic step for advancing the state of video game swordplay? If Clang is open-sourced, it might not be an unrealistic task for somebody to hack up an imperfect Kinect version for people to try out. If Clang "wasn't fun" with it's own controller, it's unlikely a Kinect version that's laggier and lacks haptic feedback will be fun either, but at least it will give people a chance to try it out. Personally, I think VR displays are the key missing ingredient for swordplay games. Seeing your stick in front of you and a sword mirroring its position on the screen is one thing, but seeing just the video game sword as though it were in your own hands is quite another! VR systems are going to have to work out low lag displays and body position data anyways but, once they do, it will pay well to be positioned to take advantage!
