The company that measures US gaming sales is called NPD, and they have access to concrete figures both for physical and also digital to a large extent. This also includes consoles.

It is of course very impressive and also explains why it is so difficult to get hold of them, they simply run out faster than Sony can make them.
Have you got a PlayStation 5 yet?
