The US is Microsoft's only strong market, but that doesn't mean this is Xbox land. The only people I know who only own an Xbone are either former 360 owners who don't really know much about either system but bought it because of the brand, or diehard Xbox fans who just really like Halo, Gears, etc. For everyone else, there isn't much of a reason to have one over the PS4. Many of my friends who owned a 360 switched to PS4. Xbox is still arguably the "cool" brand here, but more people who make an informed buying decision are ending up with the PS4.
