So to get the ball rolling here's a quote from the latest GI podcast; a Q&A with Todd Howard about Skyrim
"Are you able to be a werewolf in Skyrim?
"We're fans of that stuff as well, and we're currently messing with all that. I don't want to commit to, 'here are the things you can change into and what they're like right now.' Not because we're not doing it, or not attempting to. I just don't know honestly where that's going to end up and how deep we're going to get into that.
We will try things, and if we don't feel it's helping the game, there are other areas we'd like to spend our time on in the game."
