Uncharted 4: A Thief's End may be the final entry in the series, according to Nolan North, the voice of hero Nathan Drake.

In an interview with IGN North spoke about the conflicting emotions of voicing Drake in the PS4 game, knowing it may be the last time he gets to do so, while also stating he hopes another studio doesn't pick up the series for a fifth title.

"It's bittersweet but at a certain point you want to go out on top," North told IGN. "If this is the last one indeed, and I believe it's the last one - nothing's confirmed, but I believe it's the last one Naughty Dog wants to do, in which case I hope somebody else doesn't pick up the mantle because they've done it so well for so long - but yeah, it's one of those things where you just have to cross that bridge when you get to it.

"I like the idea of going out on top so we better do a hell of a job with this one... and it's already looking pretty good."

Sony showed footage for Uncharted 4: A Thief's Tale during its E3 press conference, which has been confirmed to be in-engine, captured from a PS4.
