Xbox one80 will take USA and UK no question. It'll be closer in those countries this generation because PS4 is launching with a price advantage and at the same time, and a proportion of people who felt betrayed by MS with the DRM crap will stay away from XB one80. So I think it'll be a 1.3:1 advantage in USA rather than a 1.6:1 advantage.
Rest of the world is PS4's though, because MS is going to take some time before it can partner with TV providers in a lot of markets, and it won't partner at all in some, so that negates a lot of the live TV selling points that XB one80 has over PS4.
