From Circana analyst Matt Piscatella’s BlueSky account:
PlayStation 5 Pro accounted for 19% of total PlayStation 5 units sold in the month and 28% of dollars. Launch month dollar sales of PlayStation 5 Pro were more than 50% higher than the November 2016 launch month sales of PlayStation 4 Pro, while units were 12% lower.
Well, yeah, you are right. They only sell at a loss initially until the hardware is old and therefore cheaper.
