Maybe they would've done a 6th series, but one or more of the actors bailed on them, and now they're just coming back to the 5 year story to kinda protect those actors.

Thing is, we don't know exactly what happened. I don't want to come to their defences, but we have to keep in mind that without those guys we never would've had Merlin in the first place.
