The xbone CANNOT sell beyond a certain point - even if everyone was excited and eager about it, it would still sell far worse than any successful console preceding it, and almost certainly not enough to survive in the current climate against the PS4. If you think that the xbone can survive with far fewer sales by default then I get what you're saying, but I don't see it myself.
That's really the big issue when it comes to the two systems, summarized in that map floating around. The service model of the Xbox One and its requirements means that there are fewer people who qualify to own one than a PS4. Sony has more potential customers than Microsoft. That the Xbox One has all those games doesn't matter if you live south of the Equator and aren't in Brazil, Austraila, or New Zealand
