That's alot of games. My question would be: in what timeframe are they all releasing? Next two years or three?

Some of these 25+ won't even release in the next 4 years probably:

-It seems like Naughty Dog is just getting started on their next game/games, as apparently the whole studio pretty much was on TLOU 2 from 2017 to 2020. TLOU 2 took 6 years to develop, from 2014 to 2020, though it didn't enter full development with the whole studio working on it until after Uncharted Lost Legacy released in 2017. With Druckmann recently implying in interviews that Naughty Dog is still trying to decide what their next big game will be (TLOU 3, a new IP, or a new game in a legacy IP), and Schreier reporting that Naughty Dog had been co-developing a new Uncharted with Bend, which might be cancelled now since Bend was asked to be moved back to being independent so that they could work on a new IP, I'd say we could be looking at as much as 5 or 6 years before the next Naughty Dog game releases (other than TLOU 2's standalone multiplayer, which has been in development for awhile already), unless that Uncharted game was in development for longer than I think and Naughty Dog decided to find a new co-development studio to take over, instead of cancelling it. 

-Sucker Punch took 6 years to develop Ghost of Tsushima, from summer 2014 to summer 2020. If Sucker Punch is doing a sequel next, it might only take like 4 years, but if they decide to do another new IP where they have to start from scratch with world building and such, it could be another 6 years before their next game releases.

-Polyphony is a notoriously slow studio, and though they will be releasing GT7 in 2022, they are reportedly working on an open world, Forza Horizon like racing game as well, and if that rumor is true, that could easily take them 4-6 years after GT7 releases to release, judging by their past release schedule.

-Guerilla Games moved into a much larger building in 2020, reportedly so that they could become a 2 team studio again. If this new 2nd team is working on a new IP, it could take them as much as 6 years to release, seeing as Horizon: Zero Dawn was in development for 6 years as a new IP.

Sony will definitely have some smaller games in the pipeline, from 1st, 2nd, and 3rd party. At least 3 of their first party studios are likely doing smaller games right now, namely Media Molecule, PixelOpus, and Japan Studio (which is just the AstroBot team now after the other teams were all laid off or retired). They will likely have more 2nd party single A and AA projects coming as well, plus you have 3rd party AA projects like Kena: Bridge of Spirits coming. 

I thought they only announced plans to expand and build a second team in 2018, but didn't actually move into a building large enough to expand until 2020.

I feel like we can guess a good many of them, let's see:

1. new Bend Studio game that Schreier recently leaked (likely new IP)
2. Guerilla Games Horizon Forbidden West
3. Guerilla Game's 2nd team game (new Killzone? new IP?)
4. Ratchet & Clank Rift Apart from Insomniac
5. Spider-Man 2 from Insomniac
6. possible Sunset Overdrive sequel from Insomniac, since Sony recently renewed the copyright
7. Next Astro game from the Astrobot Sony Japan team, the only team left at Sony Japan Studio now
8. PSVR 2.0 Game from London Studio (likely new IP)
9. Next Media Molecule project (likely new IP)
10. The Last of Us 2 standalone multiplayer
11. The Last of Us 3 (recently confirmed to be in early development by Druckmann)
12. The next Uncharted that Schreier said Naughty Dog was co-developing with Bend, before Bend asked to be moved off of it to develop their own game, assuming they found a new co-development partner studio (2nd party studio?) instead of cancelling it outright (I hope they didn't cancel it)
13. next game from PixelOpus (likely new IP)
14. GT7, from Polyphony
15. the open world Forza Horizon clone GT game that was leaked to be in early development, from Polyphony
16. God of War 5, from Sony Santa Monica
17. MLB The Show 2022, from Sony San Diego
18. Sucker Punch next game (hopefully Ghost of Tsushima sequel, but could be a new IP or a new Infamous)

19. Likely new IP from Bluepoint Games (supposedly they have been wanting to make a new IP of their own instead of continuing to do nothing but remakes/remasters for Sony)

That leaves 6+ unknown games, some are probably PS VR 2.0 games, the others 2nd party games for PS5, most of which will have to be new IP for the "more than half are new IP" to be true. 

Most of the new IPs will be small fluff games, so the number alone doesn't really excite me. Here's hoping that there will be some new hits from the big guns.

Curious, is that including the few games already released from the 25 or starting from now? 25 is a lot of titles coming out from now if so.
