There really isn't a possibility that Game Pass on Playstation would be more profitable to Sony than just sticking to PS Now.
I think Game Pass and PlayStation Now are two really different services. PlayStation Now allow people to play some old games everywhere and to download some of them. Streaming is the core concept of it.
Game Pass allow people to play some new games, day one. It will be available on streaming one day, but it isn't the core concept at all.
And people who subscribe to Xbox Game Pass do it mostly for games published by Microsoft. Those games wouldn't be available on PlayStation Now (as games included in EA Access).
I ask again, what business sense does it make for sony, to kill off their own "console-free service" and help MS build out theirs while at the same time shooting themselves in the foot by reducing how many games are sold on their platform since all gamers would have to do is just pay for a game pass subscription?
I don't see the difference between a game sold (on which Sony has 30% of the revenue) and a game available in a subscription service (Sony would have 30% of the revenue of this subscription fee).
And, again, no: Game Pass and PlayStation Now aren't direct competitors. They are two different services.
So they don't allow XCloud but they are okey with Game Pass??
If xCloud is available on every TV, I don't see why they would need to be include on PlayStation. The same isn't true for Xbox Game Pass (games can be download).
The difference is that XGP offers games from all publishers while EA Access is limited to just EA published titles. XGP is simply never coming to a PlayStation console unless just like EA Access it's limited to just Xbox Game Studios published titles, as long as it offers titles from all publishers it's direct competitor of Sony's own PlayStation Now.
People who subscribe to Xbox Game Pass do it mostly for games published by Microsoft. I don't know if it would be viable without third party games, but in the future it could be.
