So far, the only new series regular joining Supernatural's season five will be Misha Collins as Castiel.  As far as Sam's demon and Dean's angel girlfriends, Anna and Ruby, they may have a different fate.

As we know there's going to be a couple deaths in the Supernatural season finale and according to Kristin Dos Santos, neither of these girls are safe.

Now for some good news.  We're going to see the always studly Jeffrey Dean Morgan as John Winchester during season four... but in photographic form only.
