It's crazy that he says the next one after this is the final update of the game. frankly i dont believe it
well you have to think about it from the dev’s view. After every update of the programs they use for making the game they have to go back through the game and fix any issues. The longer the game is the more time it takes to redo old content instead of making new content for the players. Hope this gives a little insight of what devs have to do.
