I hope they give another director than Neil a chance to make a new game. As talented as he is, I dont want him to make all ND games.Naughty Dog currently has 7 directors: (like half of these are creative directors and half are game directors.)
Matthew Gallant, Shaun Escayg => The Last of Us Part 1, not sure what they're doing now.
Vinit Agarwal, Anthony Newman => The Last of Us Multiplayer
Kurt Margenau, Neil Druckmann, Anthony Newman => seems likely they're working on a new IP.
