Two interesting bits of news for the Supernatural viewers here in the forum. We are few, but we're dedicated. 
First-
Katie Cassidy let go from Supernatural
So, it's not just Bela that will be leaving after all. However, this time it's due to budget cuts. Phooey.
I thought Ruby was a great addition as a character.
Second-
In a more positive piece of news, we're still not guaranteed a fifth season, but Warner Bros. television seems pretty happy with Eric Kripke even if the CW suits ignore him in favor of Gossip Girl and more Gossip Girl. He just inked a two year deal with them. Given the fact that Warner produces Supernatural, that doesn't hurt SPN's chances of a fifth season renewal. A CW collapse may, but this won't.
