Dwemeri stuff is your best bet.

I think we have yet to see any of the iconic materials from previous games. I hope they are saving the best for last.

(Bonemold cuirass + shield, Telvanni Cephalopod helmet and an exquisite skirt, please.)

Its the medium armours I really want to see but the heavy armours look great. For me, High Elf, Dark Elf then Nord (minus its hat). All the others aren't far behind them at all, overall very impressive.
