In an interview with Turkish outfit Multiplayer Euroasian software market manager Sercan Sülün said that The Last of Us from Naughty Dog was coming to PS4 - both as a digital and physical release this summer. With enhanced graphics to boot.
IGN translated his comments as follows:
"There is no information about a new The Last of Us game but I can share this knowledge; as of this summer, The Last of Us will be on the PS4. Both on PSN and physically."
"The PS4 version will also include the DLC so you will be able to play 'Left Behind' as well."
Even if it's not official word, you'd expect the Euroasian software market manager to be in the know. Chances are he was just speaking out of turn and that this is indeed happening.
