Morgana will die. That much is certain, there's no way she should live or be allowed to live in the world of Merlin. Maybe not all of what she became is her fault, but a huge portion is, and it doesn't erase her crimes.

I think Kilgarah will die, but not before defeating tons of Saxons, and saving Aithusa and turn her to the path of light, where she will be Merlin's new Dragon.

Gaius lives, Gwen lives, Arthur lives, Mordred either dies or turns on Morgana and works with Arthur again.

Magic is allowed in Camelot again.

Where they go with Merlin is the point of greatest debate though. Does he die, and like Kilgarah, saves Mordred and turns him to the path of goodness, and Arthur and Mordred guide the land to peace, and Arthur never finds out about Merlin's magic?

Or is Merlin trapped in his Dragoon body forever, and Arthur thinks Merlin died as a brave man in battle?

Or, in the most likely scenario, Merlin and Arthur defeat all evil, Arthur finds out but gives Merlin a bro hug and they work it out and we are left with a happy, if not uninspiring ending.
