I doubt it. I read an interview with Colin Morgan, and he said the ending had a twist to it, but he thinks fans will be happy with it. I'm taking his word for it. So I'm guessing it will have a happy/sad ending where Arthur dies, Merlin kills Morgana and saves Camalot. Also in the legend Arthur and Mordred kill each other. I hope they add that in there. I think all these "spiolers" of yours are either made up or a rumor.
