Sony building walls around its ecosystem is going to be its downfall. If they dropped exclusives and went full on PC it could save them, but anything short of that is going to be bad for them.
Last gen about half of my friends didn't get the new playstation after owning the PS4.
Typically we have all had consoles and PC's, but they have finally decided to drop the sony ecosystem. Some of them even bought series-s box with gamepass for their kids.... I mean even Microsoft allows crossplay as much as possible, which Sony is reluctant to do.
The other half of my friends with playstation 5's have said that they are not going forward with the PS6.
Sony is on a death spiral as far as the playstation brand goes. As players switch away, it's going to speed up the decline as the people left will leave the platform to play with others.
Open up PSVR, make a commitment to crossplay, and stop the exclusives and PlayStation can thrive again and grow, not decline.
