Honestly, and Todd Howard himself has expressed this opinion, Bethesda is not really into remasters, the main reasoning behind that being they'd rather focus on the project ahead than go behind. Personally I applaud this, there is simply too many companies making too many remasters. Don't get me wrong however, this does not mean that a remaster is out of the table, Bethesda's publishing could always assign a separate developer to work on such, although errors might be bound to occur. But if ANY ES game were to be remastered, it should be Morrowind, not Skyrim, for obvious reasoning.
