I think it still has plenty of time but it is creatively bankrupt. You will know when it is getting close when a new expansion hits and the bump that comes with it is tragically low because that is what they even make the game for anymore. Once that spike becomes a hump is when they will start to re-evaluate the purpose of pumping out expansions and putting it into maintenance mode. Again, it will still be a while down the road I think. But that day is getting closer and closer.
