Plenty of games too. SIE's got "over 25" games in development. Based on looking at everything each studio is working on, we can conclude that's just from their first party studios alone.
In addition to that, XDEV is working with a lot of third party studios on first party titles. Some of those include:
Arrowhead (Helldivers 2)
Haven (before they became first party)
Team Ninja (Rise of the Ronin)
SHIFT UP (Stellar Blade)
First Contact Entertainment (Firewall Ultra)
They've also expanded their China Hero Project and are publishing games like Lost Soul Aside and Convallaria. Phase 1 of China Hero Project began in 2016 and phase 2 in 2018. They recently announces the beginning of phase 3 which will be significantly larger than the previous phases and that's where they announced publishing the two aforementioned games. Source
Speaking more broadly, they've got over 10 live service games in development scheduled to release before the end of FY25. They're investing in mobile development which will no doubt also share some overlap with the live service initiative.
They've been massively growing all their studios over the past 3 years with new hires and several are now multi-project meaning they can fully develop more than 1 game at a time, increasing their overall output. They've acquired more studios in the past 3 years than they have in any other period in SIE's history. More first party developers equals more games.
They've been bringing their games to PC in a major way for the first time since Jimbo took over, introducing their content to a brand new audience.
They've also been growing their support infrastructure for all these games and new studios and collaborations by acquiring studios like Nixxes, Valkyrie and forming PS Studios Malaysia.
So... yeah, everything including
