Were there stock issues for the switch? Like it sold surprisingly less than last week and would have easily defeated ps5 even if it stayed even.
I'm pretty sure they are holding back some stock for the double releases of Age of Calamity and Momotaro this week. So probably we'll reach 150k, if not more that week.
