Didn't Sony say they were ahead 2-1 in the US and at least 3-1 in Europe? If that was true where would Microsoft be making up the numbers?
PS4 isn't ahead 2-1 in the U.S.. Maybe during the first five months of 2017 only but definitely not overall. The split between Xbox One and PS4 in the U.S. is around 45/55 the last time I checked.
