I will buying an Xbox One this year. I already have the money saved for it. (I think it'll be around $499). I want to play the next two Halo games and my wife and I play a lot of Kinect. We use Nike trainer, Dance Central 3, and Zumba fitness as regular parts of our workout (especially in the hot phoenix summer).
I don't mind not being able to play used games. Maybe developers will get more money out of this. The gaming community has a lot of pirates and freeloaders and I don't mind the game industry fighting back. Gaming is an expensive hobby so complaining you don't have enough money to get all the titles you want new is like saying you can't afford all the nice restaurants that are out there. If you can't afford the hobby, that's not the hobby's fault.
