Sony has said that Uncharted 4's development schedule won't be negatively impacted by the second high-profile staff departure from Naughty Dog this month.
In early March, Sony confirmed that Uncharted director Amy Hennig had left the first-party studio, and on Thursday it was revealed that Uncharted PS4 game director Justin Richmond had also departed the company.
Echoing a statement released following Hennig's exit from Naughty Dog, a Sony Computer Entertainment America representative told Game Informer: "The development timeline of Uncharted will not be impacted."
Earlier this month, Naughty Dog co-presidents Evan Wells and Christophe Balestra released a statement denying claims that Hennig had been "forced out" of the company by The Last of Us leads Neil Druckmann and Bruce Straley.
Naughty Dog creative director Druckmann recently said there's a 50/50 chance that a The Last of Us sequel will be developed, while a PS4 version of the original is expected to be released this summer.
Little has been said about the next Uncharted game since Sony first teased the title with a trailer on the eve of PS4's North American release in November 2013.
