It was probably a statistical tie with the Xbox in the +5% range. Enough to say it outsold the PS4, but not enough to say "We conclusively outsold the PS4". Since NDP could be wrong with their stats slightly and the PS4 could possibly have outsold the Xbox One + fam. Either that or Greenberg needs to get fired ASAP cause they're paying him millions of dollars a year to sit at his desk and not understand what his job is.
