You are probably missing the fact that PS4 became obsolete the same year it was launched and it couldn’t be otherwise. They can’t change the console capabilities, because games would not take advantage of it, as a ps4 game need to run in all ps4 versions. If you want to upgrade the hardware, you have to launch a new product, as they are doing with ps5. It’s all about having a stable ecosystem which allows developers to spend hundred of millions and be sure to reach all ps4 users. And milk that cow for years. The same will happen with ps5: incredible machine at launch, obsolete within 1 or 2 years, but will remain in the market as is for 7-8 years while development houses (and users) reap the benefits of the ecosystem.
