I know it may have been previously brought up (i am new to the forums btw), however in the official trailer, there looked like a new type of weapon apart from the dragonbone (which was obvious on the bow and arrow seen). I saw at least three new different 'silver' looking weapons, the bow when the vampire turns into bats, the dawnguard woman weilding a silver looking warhammer, and the axe where mounted combat is shown. (this axe maybe the same one used to hack the falmer's neck). also, silver works well against undead, like vampires, so i tihnk it is a new branch of weaponary from the dawnguards arsenal. Anyone agree/disagree/have any other theories on this?
