Xbox One outselling PS4 worldwide? LOL.
They couldn't outsell PS2 with the Original Xbox, nor could they even surpass PS3 with Xbox 360, despite the 360 having a year headstart (A year & a half headstart in Europe) along with the $200 price advantage, so why would this change for Xbox One?
The Playstation brand is far stronger than the Xbox brand is worldwide. Plus Sony have always delivered in 1st/2nd party exclusives since the PS1 days.
