My gut feeling is that this would be more of an advantage for Sony than it would be for Microsoft, if it did happen, and I think that despite all Microsoft’s talk about wanting Game Pass and their titles everywhere, they still may draw the line at PlayStation. This would also complicate sales of third party games that are both for sale on PlayStation and offered free on Game Pass. Game Pass chokes out your own subscription/streaming ambitions.

This would cut into PS Plus and PS Now or whatever Spartacus combination that happens between those soon. Sony: It would be somewhat humiliating to recognize the dominance of Xbox Game Pass by accepting it into the PlayStation ecosystem, essentially surrendering the entire subscription service side of the business. You expand Game Pass’s reach while possibly killing off the entire need for an Xbox at all.

You have just paid $80 billion for a bunch of developers and all those games are now going directly on your competitor’s platform. Microsoft: Renders the actual Xbox more or less totally inert, because a Game Pass-accessible PlayStation is just…empirically better, given that all Sony’s offerings are there as well. But I think there’s a way of looking at this that’s Lose-Lose instead:
