Uncharted and The Last of Us developer Naughty Dog is working with a number of other PlayStation Studios teams to develop a mysterious new project in a "beloved franchise".
That's according to a newly spotted Sony job listing (thanks VGC) seeking a game design intern to work at a "new PlayStation studio based in San Diego... co-developing an exciting new project with Naughty Dog in a beloved franchise." There's no additional information about the new studio, but it seems highly likely it's the same San-Diego-based "new internal game develop team" Sony referenced in a different job listing earlier this week.
That earlier job advert initially revealed the new team was being built to collaborate on a new "high visibility" project with Naughty Dog and Visual Arts - Sony's San-Diego-based support studio that most recently worked with Naughty Dog on its The Last of Us: Part 1 remake. However, a later edit removed the explicit reference to Visual Arts, for reasons unknown.
