I would think demand is down some just from it being after Christmas, hopefully, making scalpers less interested. I don't think you'll be able to get them in most stores until online stock and availability increases a good amount. Hopefully, over the next month or at most two.
Most stores don't want to carry it because they don't want large gatherings due to COVID. New generation hype, manufacturing slowness/complications (probably due to COVID), higher than expected demand (probably due to more people playing games than usual...again COVID related), and bots/scalpers buying up a good chunk of the stock has made this the perfect shit storm. Same thing is happening with computer video cards and processors.
