Guys, I've known the truth for a long time now.
Truth is, Jak 4 is being made. Yup, I said it, Jak 4 is being made. This caused a civil war so to speak due to one part of the team wanting to make a open world platformer akin to Arkham City, but with the scale of a GTA game. The other part of Naughty Dog wanted to make a Dark Souls-esque Jak game where the platforming is extremely tough and the world is interconnected, the player can find shortcuts or create them. This creative rift has put the entire team on edge and a lot of people are backing out. Other creative arguments included if Daxter should be in the game, if it would be a sequel or reboot, whether or not to include vehicles, the whole thing is a mess.
I know what what you're thinking, and yes, I know this because I've read tweets and can interpret them with no error. This is the closest thing to the truth and I'm worried.
