it takes a while, I think it took few/several months to get the colossal titan update out after annie, and then several weeks or a few more months after that to get trost out. It's only two guys, trying to program and update the game so itd take a while for them to do even one thing. Also, many site hackers have been attacking the game, so they have to run maintenances and reboot the game after attacks, its all pretty time consuming.
