I doubt there will be a season 6. One they are repeating the same plot devices too many times; and two, the declining ratings for Merlin this season. They are leaking out episodes two to three chapters ahead, as if they are trying very hard to keep viewers engaged. BBC is a business first. If the sagging ratings is putting a drag on the company's profits they are going to end the show with season 5.
