While the screenshots haven't officially been released by Sony to online press, they were spotted on a website by NeoGAF users and their legitimacy was seemingly verified by Naughty Dog community strategist Arne Meyer in a subsequent post on the gaming forum.
He said: "I think those screens were from the batch we sent for a print only feature in Japan. They may have been accidentally distributed. We'll see what happened, but regardless enjoy!"
Sony announced a The Last of Us Remastered release date of July 29 at E3 in June.
