I liked the Dwemer weapons in Morrowind since they had a slight steampunk-ish feel to them, and as for armor it's sort of a tie between Ebony and Chitin (IIRC that was the white bone-ish armor right? haven't played MW in a long time). I would really like to see both of them in Skyrim, and not just remakes of the old style but new designs (that goes for all the armor, but I doubt they will use recycled styles).
