Naughty Dog is now one of the internal studios of PlayStation Studios, which has not yet officially announced its next game. So one of the insiders decided to do it instead.
Twitter user ViewerAnon, who has repeatedly reported on movies and games ahead of the official announcement, announced the ongoing development of The Last of Us Part III, which is being led by Neil Drackmann (game director of the first two parts).
By the way, the American game designer has previously made several hints about the possible development of a third part. And in June of this year, he revealed that his next game is already in production, and promised to present it at the Summer Game Fest in 2023.
Also, the insider mentioned that the Uncharted reboot is being handled by another studio, not Naughty Dog. He also revealed that the multiplayer game in The Last of Us universe will be released before other Naughty Dog projects.
Of course, all of the above insider information should be viewed with a degree of skepticism, as neither Sony nor Naughty Dog have made any such claims.
