I worked at Microsoft when the first Kinect came out. I spoke with a few members of that team (non-engineers). My question was very clear -- are you expecting this to takeover for controller based gaming? I don't recall all the responses, but I think the overall sentiment was along the lines of "No, but it might", whereas my thoughts were along the lines of it absolutely will not, this is such a gimmick. I'm not a gamer at all, but I used to be in college. When I want to game, I plop down on my couch and mash on the controller. If I wanted to jump around and flail my arms, I'd go to the gym or play some pickup basketball.
I think there was (maybe is) a disconnect between Microsoft and hardcore gamers. Kinect and Xbox One's initial non-gaming features were an attempt to take Xbox "mainstream". Stop it. Appeal to the core demographic. To their credit, it seems like they've been doing that now.
