The PS4 version outsold the Xbox One version while the Xbox One version had official bundles and marketing. You know this, Kerotan. Now the tables have been turned and PS has the marketing deal back, it's not really surprising to see the PS4 version maintain a healthy lead over other platforms (Specifically legacy and Switch platforms) and probably extend that lead as the PS4's actual marketshare also increases.
Why are people acting surprised by this, or trying to make up silly excuses? Just look at how FIFA 18, FIFA 17, FIFA 16, etc. have all performed on specific platforms. You're on a sales website.
Worldwide, FIFA 18 on PS4 sold more in a single week than the Xbox One and Switch versions sold lifetime combined going by data available on this website.
