Whatever you feel about Naughty Dog's actual games, I feel like it's a bit odd to call them out specifically for not releasing games consistently. If anything they've done a great job of staying consistent with game releases despite game development taking longer and being more expensive.
TLOU Remastered is a great port that was developed in-house and allowed them to get more used to the PS4's tech, so I feel like it should count, especially because it's a PS3 game that was developed on very different architecture.
They basically made two different Uncharted games already.
And they have TLOU 2 coming, and probably a new IP.
That's four games this gen.
