According to a Turkish website Multiplayer The Last Of Us will be making its debut on the PS4 this summer with the single player DLC Left Behind. The news originated from a NeoGAF post from NeoGAF user Quirah.
Quirah translated a quote from PlayStation Turkey’s VP Sercan Sulun when the question was asked about a sequel for The Last Of Us:
Will we see the The Last of Us sequel soon?” and he replied, “No, sequel is not coming right now as far as I know but I can say that first game will be released this summer for PS4 as a physical and digital copy, with enhanced graphics.
Now while i don’t speak or understand Turkish, an IGN reader translated the quote a lot more thoroughly:
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.
So nothing set in stone just yet but this is definitely one we plan to keep our eye on.
