I kind of hope for PC version although I prefer it to be handled via SteamVR (or OculusSDK or WMR SDK) than just dealing with specific device's libraries.
There could be even gloves that use the same system. While gloves kind of contradict the whole idea (to have nothing in your hands), they could be much more precise and could not have as many problems as camera-based hand-tracking currently has. Of course those don't have to be gloves, it can be something that you just put on your hand - I think that I've seen something like that, I just can't remember the name.
