They're never going to as long as we all keep playing the game. I know longer play regularly anymore i have too many animals in storage and the cost for the habitats is utterly REDICULOUS the game is no fun anymore. It takes too long to expand and too much gold to upgrade. And way too long to even go up a level. So I know go in once a day to collect. I no longer participate in events I've yet to finish even one there isn't enough time to do them. So I'm pretty much done with this game.
