I mean, if PlayStation Plus doesn't take off on PC or mobile, I don't see how losing console market share is worth selling to more consumers. On PC, Sony really only makes money on their software and MTX, compared to their own platform where they make money on every game sold, first party software, accessories, a cut from every DLC/MTX, PS+ Extra & Premium, multiplayer paywall, etc. Sony's single player games would need to sell astronomically better for it to be worth going Day and Date on PC. 

Even a hypothetical Sony launcher on PC would be facing major challenges. They would need PlayStation Plus to take off, or at the very least compensate for the loss of subscriptions as well as consumer spending, that would come with losing 20M+ users from their console base. If PC GamePass is any indication, just being available on PC doesn't mean you'll automatically have growth, yet alone growth that is more lucrative than a walled garden ecosystem.

And just to note, I think Sony's strategy for mobile will be drastically different than their strategy for consoles/PC. 

GT7 is low-key Sony's 2nd most impressive seller (Helldivers 2 being the 1st obviously) this generation, looking at its legs. And I think it alongside Bloodborne and maybe Demon's Souls have serious potential on PC, but Sony just refuse to port their Japanese games to PC for some reason.

I think they're coming but it is bizzare how long it's taking them.

Amazing numbers. Jim Ryan's parting gift, no one thought he'd be vindicated this quickly. Can you imagine if Concord pull in similar numbers? huge. Destiny 2 is back on track as well, it will be interesting to see how the finale shape does.

With that said, SONY is at a crossroads here, they either do what MS, which would be short-term-ist and infinitely more stupid because the brand PS was never as weak as the Xbox brand, especially now. The other option is to learn from Nintendo, the entire industry is admitting how stupid they've been and eagerly waiting for the Switch 2 to save their failing business models.

And to be clear, for SONY, learning from Nintendo doesn't mean making more AA games, imo it means doubling down on what the PS brand identity is right now, more AAAA games. Not only they know how to make them with consistency, but they have the expertise to translate them to multimedia franchises.

PS studios never made great AA games to begin with, they all sucked and didn't age well at all. Only two franchises have lived on for generations, GT and GoW, and even GoW had to rebooted to stay relevant, which is crazy giving how successful the PS/PS2 were. They need more people and more new studios working on such games which I am not seeing at all and that's the glaring problem imo.

Sony's "very different" games are typically published just like Helldivers is. Bloodborne, Sackboy, Stellar Blade, Lost Soul Aside, and Destruction AllStars are radically different from what Sony develops in house.

I think they know full well that their upcoming live service games need to have a wider variety than their singleplayer games. There will still be a number of similar-ish games of course, but hopefully the variety is wide enough, with some being made by Japan, China and Korea.

The thing is thats their entire brand..... Playstation is important to Sony.
It lives and dies, on its exclusives carrying it.

Day1, makes sense for GaaS type games, and heavily multiplayer focused ones..... not so much for big AAA single player story focused experiances.
If they did that, it would end up loseing them playstation console sales and subscriptions.  I'm not sure that trade for, for slightly more sales on PC is worth it.

I think keeping to a 1year down the line, for story based games, is fine.
There has to be a reason to owning a game console, and that has to be based in games (ei. a console cant just live on services like gamepass imo).

Theres like 34m gamepass subscriptions.
Thats probably like 20-25m from series x/s, and maybe 5-10m from older gen (xbox one's), and then like 4-5m on pc.

Yes its successfull on pc.... but the vast majority of gamepass subscriptions are on console.

These aren't absurd numbers, but they are great numbers we've seen 20 and 15 million units sellers in 3 days. Hell divers is doing great, but we've seen quicker and higher sales in the past.

I think it's dangerous to disincentivise buying your hardware especially for Sony. Basically it's as followed 

1. Pc ports to boost sales but gives people an option not to buy sony
2. With pc ports eventually those pc ports will run better then the ps5 versions hurting sales more
3. 3rd party games that would be sold on your platform could be bought by the same people on steam where they know they'll have it years later 
4. 3rd party titles that would go to ps5 don't because it's less enticing when pc and other consoles sell better 
5. Less 3rd party games (especially exclusives) will hurt because the 30% they get and for a company like Sony who make more from 3rd party they will be hurting
6. With less sales of hardware and software Sony will either have to lower development costs by making smaller games or they'll have to make pc ports more appealing by launching them closer to maximize hype the game receives. 

I do think that for a platform holder doing this in the long run will hurt them. 

It's too early to call the game a success as a live service title.  Obviously big up front sales is very important. But the goal of a live service game is to keep making money for several years. I think it will be at least a year from now before we know if that's going to happen. 

Certainly Sony is happy to see the game selling. And at this point you would probably bet that it will be a successful game in the long-term. But it hasn't actually achieved that success yet.
