Here is my take on it, the recording software on the xbox is just going to make it so 11 year olds hyped on too much caffeine can make 'lets plays'. Not going to be very good for the gaming community on that part, Kinect was terrible and the designs will always be terrible. You can't make the kinect good in anyway possible with the microphone to tv interference, low quality video, its just a bad idea all around. I own a PC where I can do everything the xbox, and playstation can do, only better, faster and multiple parts at the same time.
With how much the xbox one is going to cost, id rather buy an entry level gaming pc.
