I've been watching another video blog about the game, and it's become apparent that these random assumptions are getting ridiculous. Seriously, just because a PR for Skyrim can neither confirm, nor deny, or even says no comment,
it does not mean there will be werewolves. They simply do not want you to know. And if they do exist, it could be a cool little side story about one of the villages plagued by some beast on a full moon and they just don't want to ruin everything. As much as I am one for wanting to know more too, there is only so much you can find before it goes too far, and ruins your entire experience. Like that one spoiler I found out before I played Wind Waker...
At any rate, discuss.
