It seriously doesn't. I'm sure Nintendo wishes the WiiU was selling as "badly" as the Xone is right now. While I'd much rather have a PS4, it's a real testament to the strength of the Xbox brand that they've shipped 5 million units given all the baggage the Xone launched with. Not to mention how the PS4 is available in far more countries to begin with.
The PS4 doing astronomically well =/= the Xbox One's sales being terrible. The PSP selling 70+ million units would still be a failure by that metric because of the DS. :p
