Not to gang up on you here, Robert, but regardless of how much/little hard data there is here, if taken as opinion, it is as valid as anyone else's. Personally, I grew really angry when articles very much like this kept hammering away about physical discs going away and leaving only streaming...
As has been going on here ever since I joined (1999). New members come aboard, old members lose track of what has been covered. At least we're here and posting and showing an interest in film.
