Then again perhaps Bethesda won't go down that road again because that's basically what the Bloodmoon expansion for Morrowind was all about but yeah.. why not?
Werewolves make no sense at all whatsoever lore wise unless a hunt of Hircine is in progress(Correct me if I'm wrong on that) so basically werewolves won't be in unless this happens.. of course there would be no room for something like that in the main game, even a very long side questline would not do it justice.. with a spear being Hircine's main weapon they would have to add them of course.
What does the forum community think of my prediction?
