A Skyrim remake? Why would they do that ... unless you mean they simply make another Elder Scrolls set in Skyrim. It would break with a tradition - always a different province.
Anyway, a lot of people think the next Elderscrolls will be set in one of the elvish isles or provinces. Which makes sense. It is yet again another location where they can play it save. High fantasy! Just never ever do something that could be considered risky! The Catpeople? Deserts? Booooooooooooooooooooooriiinngggggggggggg! Or the Lizardvolk? All in jungle and swamps? Naw! To hard on the brains of people. It needs woods, castles, and allt hat LotR shenaningans. Can't dare to make something that could even remotely unique. Well what is really unique in this day and age? But still playing with Bethesda, the last visually unique game they made, was Morrowind.
