Why would physical copies matter for this? All physical games have to be signed by Sony anyways so it's not like a third-party can produce them.
They'll be forced to embed alternative stores in the PlayStation.
I won't wait for it though. After 28 years of always having a Sony at home, it ends here for me at the age of 35.
Retailer exclusion. Monopoly behavior. Total market control of goods.
That doesn’t matter. It’s about the end-users perspective in that case. You can sell physical copies in physical stores or online on competitive pricing. The main point is that the customer has a choice. As soon as the physical discs vanish, they won’t. And that’s where gatekeeping starts.
