I think that Dylan is confirmed as having signed to film S4, so Stiles is not likely to be the death unless he is going to become the werewolf's ghost sidekick (and hasn't that been done before?).

That leaves Allison and Derek, as neither Crystal or Tyler H. are supposedly confirmed yet.

If it is Allison, I couldn't care less. She's becoming a Mary Sue and it's ridiculous. Also, Crystal is just not passing well as a teenager anymore. She's now 29 and in most of her scenes it's visible.

Derek would be a bigger loss for the show, since he is basically the alternate protagonist. I don't think you can really have Teen Wolf without Derek, even though he is not a teen. A huge chunk of the show's popularity can be credited to him.
