DS2 is made by Kojima. A third party studio.
Sony first party was MIA aside from Horizon DLC.
DS2 is published by Sony, and it's a Sony brand, so it's a first party game. In addition to the Horizon DLC and DS2, Sony also announced the Returnal and TLOU PC ports.
When a 1st party game is developed by a 3rd party studio, it's also called 2nd party game, but still is a 1st party game.
Considering they delayed their games to put them all together in 2023, they will likely have something.
But the real question that most should be asking is, where are the 2023 games? Starfield, Redfall, etc. were supposed to release in 2022. So what did they plan to have in 2023, and when are those games releasing?
Due to Covid lockdowns most AAA games under development back then got an aprox. half a year or a year delay. Meaning a lot of games originally planned for 2021 were delayed to 2022, the originally 2022 games delayed to 2023, the 2023 games to 2024 and the 2024 to 2025. Not only for them, but for basically all AAA publishers.
The thing is that most games affected by this still weren't announced or at least didn't announce its release date when were delayed, o in most cases you won't notice it and was only noticeable in the games that had date announced, like the 2021 Sony games pushed to 2022 or the MS 2022 games pushed to 2023.
Well you have to understand that they have a lot planned to show for 2023, and you will not have to wait too long for what’s next for them.
I think they'll show mostly already seen games and a lot of indies that will debut on GP. Plus -once the regulator investigations get completed- a console and GP price increase, specially if the acquisition gets approved.
There is nothing consistent about Sony right now. They skipped E3 and skipped their september show which was their one consistent show the last two years. Even you told me that them skipping September means i should wait till the VGAs. Well, they showed up with DS2 and Horizon DLC. Better than MS but MS is abysmal so thats not saying much. Especially after skipping an entire year.
There's something consistent about Sony that when looking the whole year gets repeated every year: they announce and release more big exclusives, and got more awards from them than the other ones. Yesterday Sony's console exclusives got a dozen awards, 7 of them for internally developed 1st party games.
In 2022 Sony made many announcements at events like CES, E3, TGS and VGA plus in many other State of Play and PS Blog posts. Not only to announce new exclusive games or PC ports of old games, but also to several acquisitions including Bungie or Haven, PSVR2, the new PS Plus, eSports stuff or OS improvements and additions like adding VRR, 1440p, PS5 Tournaments, or the start fo Discord support and PS1 + PSP emulation.
