I would love to see Dragonbone weapons...hmpf..i can't understand why they didn't make them in the first place..Two handed sword made of a dragons jaw!...Dragonbone bow!
But my hopes are pretty low..we probably wont see any dragonbone weapons.

I would love to see a expension focusing on the shapeshifters,werewolves and werebears.Complete with a shapeshifter skill tree and questline...maybe a new faction for shapeshifters!
To be honest i have no idea what the DLC will be like.
It could be anything,from the stuff we saw in the game jam vid,to summerset isles kicking Thalmor butts.

Maybe we get to visit solstheim again?Who knows,i just hope it arrives soon!
