As others have said, Sony significantly expanded their internal teams before the launch of the PS5: Santa Monica, Naughty Dog, Guerrilla Games, Insomniac Games, Firesprite & Bungie have multiple projects in the works.
Sony has built a support studio in Malaysia, as well as acquire smaller teams like Valkyrie and Fabrik, to make first party development more efficient. They even have a dedicated PC studio in Nixxes to focus on ports. PlayStation is ahead of the industry when it comes to internal engines/support pipelines/studio collaboration which will pay massive dividends by the end of this generation.
