In the post-credits scene we see Nathan Drake and Sully meet with a shady-looking, eyepatch-sporting Pilou Asbaek, and they’re discussing their potential next big job, which Sully says could be the big one. There’s mention of a Nazi treasure map and another character simply called Roman - both of which are pretty solid references to the very first game in the franchise, Uncharted: Drake’s Fortune.
In that game, Nate, Sully and Elena Fisher - Nate’s future wife - search for the lost treasure of El Dorado, and encounter - among other things - a Nazi U-boat in the jungle, as well as a German U-boat station in a race against rival treasure hunter, Gabriel Roman - potentially the Roman who’s namechecked in this scene.
