The age of exclusives died when consoles connected to the internet. (Minus Nintendo)
Once people could play with others from the comfort of the sofa it was wrap, people just didn't realize it yet. Friends bought systems to play with other friends that had the same system, exclusives were just a bonus even though playstation did its best to try to make it feel like it was the main thing.
Fast-forward to 2025 and it's expected that Sony drops these movie game cinematic experiences at least every couple years. Sadly those games cost hundreds of millions to make and years to develop and the return on investments is getting worse and worse.
Even the high even double A games aren't really trying to risk it being exclusive to a console unless they really are getting a bag.
Sony trying to lock down 3rd party exclusives will continue to get more expensive, and make less sense as the years roll by.
And if steam and Xbox end up as cool as Phil and Gabe are IRL...

I don't see any other choice but PlayStation adopting steam on its console as well.
