The PS4 is one of the best-selling game platforms of all-time. It's currently sitting at about 117.02 million units sold. During the Week of 01 Apr 2023 it sold about 3,700 units. It will likely get discontinued globally at some point this year, or at least in 2024 I would think.
PS4 helped Sony immensely after the massive amount of money lost by the PS3 and the failure of PlayStation Vita. In the U.S., PS4 Slim and PS4 Pro never got price cuts. I understand that the Slim goes on sale at major retailers at least yearly for around $200-$250. But that's not the same as a permanent price cut. The PS4 Pro had some good deals at times as well but maintained an official price of $399.99.
There of course is the Global Supply Chain Crisis which seems to have hurt PS4 sales more than helped. While more people spent more time indoors playing games, PS4s were tougher to produce and so were PS5 consoles (Sony's priority).
From where the PS4 is sitting right now, it's effectively finished in terms of units sold. It might not have 250,000 units left in it at this point.
How Much Could PS4 Have Sold Without the Global Supply Chain Crisis? And is there anyone who thinks it would've sold less without it?
