I'm stoked to see that werewolves will be making a return in Skyrim. They certainly fit in with Solstheim, so it would make plenty of sense for them to be present in Skyrim.
I'm eagerly counting down the days to the release of this. Easily my most anticipated game of the year.
I personally hope vampires and werewolves make it to Skyrim. I could personally care less about weapon degradation and stat simplification since I think they will make the game-play better. I will definitely add many mods to Skyrim over the course of time, I just hope it's much better then Oblivion's System which got very complicated over time.
