Well, we always need more weapons and armors. There should several sets of of weapon/armor of each material.
But in fact I don't worry about that too much. There will be mod. And I will make my own weapon and armor for fun ,just like the old days.
I think you are right about the material thing. Ebony, for example, could be crafted in mant styles. The same goes for steel, mithril, daedric(cursed(?) ebony) etc.
Having nordic and orcish forged steel(normal orcish armor is in fact this), ebony armor and weapons etc.
I hope they include many armor and weapon types of each material being a consolegamer I can't use mods.
