With how much AAA games cost these days, I wouldn't be surprise if exclusives slowly become a thing of the past (Beside Nintendo maybe).
You have a powerful console for those you like consoles with PlayStation
You have GamePass for those who prefers the Sub/Cloud Service model with XBox
You Have Nintendo you know... for Nintendo stuff
And you have PC for those who prefer PC (mods, kb&m, etc...)
Nobody's stepping on each other business, games cost hundreds of millions to make so let's just put them everywhere or just keep them as temporary exclusives.
It make sense.
This is the reality. You can't really spend 200 million dollars on a game and leave tens of millions of not hundreds of millions of dollars of revenue on the shelf just to prop up a plastic box that is already selling itself.
Exclusivity doesn't really matter to Sony, especially if they can still sell PS5s.
What matters even more is if they can sell PS+ on mobile and PC and if they can create a PC and Mobile Storefront where they a) don't have to revenue share with Valve, Apple, Google, and Epic and b) where they can actually generate additional revenue from 3rd party sales on those platforms.
That's how PlayStation goes from being valued at around 45-65 billion to being valued at 100+ billion.
Eventually their revenue in non-core business could outmatch their core business.
Amazon started out as an online book store, Marvel started out as a comic book company, and Nvidia was just a graphics card company.
PS5 is going to sell even faster than PS4 despite Sony putting games on PC and Mobile. The revenue that they generate from these other mediums will allow them to sustain a rather unsustainable path with AAA gaming, especially since they understand that they can turn these AAA games into movies and tv shows, that will generate more sales.
IP generation is the most important thing you can do and that is why Sony is looking at Day's Gone, Bloodborne, and Gravity Rush. If even one of these can hit like Cyberpunk Edgerunners, you can sell millions of copies of software that you otherwise couldn't have. That's why these games are no longer available on PS+ Collection and why eventually we might see remasters/remakes of these games. Yeah I know Gravity Rush was already remastered.
