Eh... I seriously doubt it is sold out everywhere in the US. I worked at Bestbuy for I think 4 Black Fridays. The last one I worked was the year that the PS4 had just come out. And even then, we had enough stock to last throughout Thursday and most of Friday.
We also had a certain allotment for Thursday night, a certain allotment for online orders, and an allotment for Friday.
Just because they're not selling it online at the moment does not mean they're completely sold out.
