I think the most logically consistent explanation for the PS4 outselling the XboxOne in the territories where the 360 outsold the PS3 are that the PS4 was cheaper at launch, had the positive mindshare of having better multiplats, and the positive publicity of having exclusive marketing deals for huge releases like Watch_Dogs and Destiny. Even after the PS3 dropped down to an equal or lower ASP than the 360 and eventually closed the gap on multiplatform games, it didn't matter, because consumers had already made up their minds. MS made the mistake of believing that the 360 fanbase was made of people loyal to their brand, rather than people loyal to what their brand had previously embodied (high end graphics and superior online play at competitive prices).
The Xbox One isn't doing nearly as poorly as the PS3, but it is currently in some grey area between it and the 360 in NA. I think that not having a true Gears or Halo sequel for this fall will really hurt its trajectory going into next year (I'm as excited as anyone for MCC, but remakes gonna remake). And they have the added bonus of every multiplat they advertise working against them, as it simply makes the PS4 more desirable.
The console will end up with tons of good games and multiplats are selling well enough that it won't lose support, but dreams of winning the online sales wars are pretty much over barring a miracle.
