You can't extrapolate like that.
Xbox is the one and only console ever that is extremely US centric. That and the year head start helped it to Win US against PS3 by a landslide.
Console ecosystems are more and more integrated now so changing a console is more and more difficult. In the past there wasn't a single thing keeping a person from changing consoles between generations. Now they have subscriptions, friends lists, achievements, familiarity. The chance that people who had an X360 will go with X1 this gen is really really high in US.
MS is willing to fight for it so US will be definitely Xbox territory. Unless of course they screw up again and make a 180 in the wrong direction.
If you demand respect or gratitude for your volunteer work, you're doing volunteering wrong.
