Pretty certain it does not need to be connected at all. The main issue the reviewers had with it was that you needed to say specific things for it to register and work (and sometimes still didnt). I will use it, I hooked up my 360 to the main tv last night as we will still use it for renting movies / xbox music and the kinect voice control worked fine....when I was within 3m of it. Was extremely hit and miss from further back. If kinect 2 can have a longer range to hear us without yelling then I don't think it will be bad at all.
