Have to wait on US stock numbers but it seems highly likely to me that Xbox outsold PS for black friday this year, globally
Yeah, I dont think it's an issue of Sony prioritizing any market over the other. Japan is randomly "prioritized" over European countries in some periods (like now, even though Ragnarok is geared towards western players).
It might be related to PS5's packaging size. Rumors have it that Sony is launching a redesigned model later next year.
