PC Gamer magazine- there's a table showing what can be equipped alongside what in the right and left hand (weapon a spell, two-handed weapon, shield and shield, etc). One of the columns is "polearm."
A halberd is also pictured in at least two pieces of concept art for the game.
Oh cool! Well a polearm is almost a spear, it's better than not having a long stick with death on one end. That makes me happier. Anything to break the monotonous sword-axe-club triumvirate of Oblivion.
Todd, I take back what I said. But we still need more Muatra!
Hey, maybe we get something like a Japanese Tonbogiri. That would be interesting. Sword with really long handle.
