Nate Wells, lead artist on The Last of Us, has left Naughty Dog to move to Giant Sparrow. He had been working at Naughty Dog for just under 2 years, and 10 months of that was spent on The Last of Us.
Giant Sparrow is the indie team that made the critically acclaimed The Unfinished Swan. The studio announced last year that they were working on Edith Finch, but retracted the news and changed the name to "Unfinished Giant Sparrow Project". The assumption is that Wells will work on this project.
