Maybe they will or it could just be the Perilous Lands, in my opinion, they look really similar.

And Saxons are going to appear in Series 5 and they are known to have fought in the Battle of Camlann.

And lastly, the trailer I was talking about was the one at Comic-Con, which was different to the others. :)
