Not to mention if we do use the Dragonborn from the trailer there are some problems. He's not a mage, theif, or assassin. Maybe he could be a companion but we never see him as a werewolf. In the Dawnguard trailer we see him as a dawnguard and a vampire. we could do the Dragonborn DLC no big deal. Not to mention we don't know if he joins the stormcloaks or Imperials. Someone needs to call Todd Howard and ask him these questions.
