So, I did some calculations and at this point last year, the PlayStation 4, Xbox One, and Nintendo Switch sold through 48.4%, 32%, and 40.3% of their respective 2017 numbers.
If those same percentages were to hold this year, these are the totals that all 3 systems would finish with.
PlayStation 4: 17,141,226
Xbox One: 9,335,112
Nintendo Switch: 16,438,757
