The Last of Us will release for PS4 by the end of 2014, according to PlayStation's Eurasian Software Marketing Manager.
According to various translations of a video presentation by Turkish PlayStation spokesperson Sercan Sulan, the game will release for PS4 in the northern Summer (or Winter in Australia).
Answering to queries regarding a sequel for The Last of Us, Sulan said there is no news on that front, but that a port of the first installment is happening.
"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," he said, as translated by IGN.
"The PS4 version will also include the DLC so you will be able to play 'Left Behind' as well."
Normally I wouldn't double dip but exceptions can be made!
