A common confusing Linkedin post that doesn't seem to align with established data. The Reddit link doesn't tell us anything about platform splits.

It's probable that PC GamePass has been comfortably outgrowing Xbox GamePass which may have actually declined in the last two years, but I doubt it's close to it yet, even without GamePass Core in the equation. The majority of active Xbox users are on GamePass, and the active userbase is a lot bigger than hardware sales suggest.

Some weird accounting shit is probably going on in this Linkedin post lol.

My thinking is that PC sales have not been majorly significant for them, and they started worrying that they might go the way of Xbox if they keep going like this. It's basically the same question, why have a Playstation/Xbox if you can get everything on PC.
They know that Nintendo's success is based mostly on exlusives, it's a first party machine. So they are thinking, don't be like Xbox, be like Nintendo and you will survive.
Of course, for that to happen, they would need to wisen up and start doing what they used to be good at and release the kind of games they built their reputation on. This travesty with GaaS needs to fade out, at least insofar as it significally hinders developing single player games.

I wonder how much their games were pirated on PC? Could that be a factor too?

I would say that is extremely unlikely, basically a non-issue IMO.

This is a shame since other than Nintendo games PC had basically everything at this point. It does make me more reluctant to get something like Ghost of Tsushima now knowing the sequel won't be coming, at least not till a potential 2nd reversal which wouldn't be anytime soon. It will give the PS6 a notable advantage in that it'll have all big blockbuster games other than Nintendo games now with Microsoft bringing their games to Playstation. Sony could have a hard time finding strong selling points for the PS6 so this would help with that. It's an interesting shift from a few years ago when PC was the only one getting both Playstation and Xbox games so was the platform to get to experience all big games other than Nintendo.

The best thing about all of this is the silly fools who were like "All Sony games will release on PC day 1 and soon." Crazy how some people struggle to understand the significance of the Playstation platform to Sony.

That said, Playstation will ultimately transform to a storefront with some if not all their games being exclusive on it. Wouldn't surprise me if the PS7 is a closed PC that only supports the "Playstation Storefront", and has the same price range and convenience of home consoles, therefore Sony wouldn't lose their core audience, and might instead become a significant force in the PC space where the store is also available outside their own hardware (Sony wouldn't care if you stop buying their hardware as long as you remain in their larger platform).

Consoles have one major weakness against PC that hardly gets discussed: It's the requirement of development kits. Recently, many of those trendy games come from indie studios that start on PC. This gives Valve/Steam a big advantage against consoles which often get these games a while after they established a large audience and connection with PC.

Now someone might say "isn't this what Microsoft is doing with the next Xbox?" The answer is not quite, because:

1. Microsoft will not be able to sell "consoles" in the tens of millions. Xbox is a dying brand and their offerings will be expensive.

2. Microsoft will allow 3rd party storefronts. This is a double-edged sword that will remove more Xbox players than it brings. The storefront, NOT the hardware, is where the real money is made. Valve will benefit more from this than MS.

3. Unless they do some radical changes, Mirosoft's games aren't locked to their paltform. Valve, Sony, Nintendo and even EpicGames (on PC) all recognize the value of their own games as platform/storefront sellers. Microsoft doesn't, they seem to care more about reach and their 3rd party aspect.

4. Sony may continue to work closely with AMD to design SoC's that are cheaper to produce with an unparalleled "power per dollar" aspect. Retaining a traditional console advantage.

Call me crazy (and I might be), but I don't even rule out Sony taking this path with the PS6. But I think doing this early would confuse and be a PR disaster.

Storefronts will branch out to more hardware, but exclusive content will never die.

I see people saying Sony need exclusives to move consoles, but the vast majority of people who buy a PlayStation 5 are doing so for 3rd Party games and Live Service games. We see charts all the time showing this. People bring up Nintendo, but they're the only ones people will buy their hardware for 1st Party games. 50% of all Switch software sales are 1st Party, Sony and Microsoft are no where near close to that. They'd be lucky if they could even hit 20%. Sony loses nothing putting their games on PC, but as I stated in a previous post they completely botched their PC strategy. They had no idea what they were doing even though there were plenty of examples of what to do and what not to do. Microsoft has a much better presence on PC than Sony even though PS fans swear Sony have the best games.

Day 1 releases would definitely hurt PS consoles sales over a long-term. Maybe not to a major extent, but it's pretty clear the delayed approach at least provides the console release a semblance or importance for ppl who play those games. And sales prove there is a large portion of ppl who buy first party titles.

The delayed approach appears to have the opposite effect for PC sales. But the options are either day 1 (which will hurt their console sales), delayed releases (which possibly isn't working) or no release (which just means no resources being put into PC ports and more into their console releases).

There is another option, delayed release at a lower price point.  Currently Sony games were delayed release at full price.  

I can only speak for myself, but paying full price for a game that is a couple years old is a touch ask.  

Day one releases will slightly hurt their console sales, but it's made up with the profits of their PC ports. If anything it will benefit Sony more. Lets say a small percent will buy a PS5 for the few exclusives it has, Sony would lose more money because that person wouldn't buy anything else on the system and not subscribe to PS+, no 3rd party sales, no microtransactions, etc. If Sony did day one releases and those people won't buy a PS5 anymore they still will get their money through their PC ports, and be able to sell to the millions of PC gamers that refused to buy a PS5.
