Will there be a Jurasic World 2

Will there be a Jurassic world 2, is a question I have thought about. It would be very cool if they did but probably not, because unlike there other movies this one actually had a proper ending. "SPOILER ALERT" they took down the indonimnus Rex, and the main evil villain died, so by the looks of it this a one time squeal for Jurassic park.
