Speaking at his own panel at MetroCon 2015, Nathan Drake voice actor Nolan North shared information he knows about both Uncharted 4: A Thief's End and Visceral Games' upcoming Star Wars game.
Asked by an attendee how ex-Naughty Dog writer Amy Hennig's departure affected Uncharted 4's development, North replied:
Hearing about how much the team from The Last of Us has altered the design of the story, which is said to conclude Nathan Drake's timeline, I get the feeling that Uncharted 4 will have a dark tone. The Uncharted series has always been playful, sometimes even cartoon-ish, in nature, but it appears that this game is going to change that one way or another.
North continued:
After talking about Uncharted 4 North was asked about Visceral's upcoming Star Wars title. He similarly couldn't say much about it, but just enough to offer insight into the direction of the game. He shared:
Visceral's Star Wars game hasn't been unveiled, but is confirmed to be in development. North made it a point to state that it isn't Star Wars 1313. Based on what he shared, you can expect a very story-driven experience with third-person action gameplay.
