Sercan Sulun - Eurasian Software Market Manager for PlayStation - told this Turkish-language webcast (around the 35-minute mark) that
"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."And that is what I call good news. The Last of Us still looks better than most next-gen offerings - this'll work out well.
