The CW has released the official guide for Season 7 of Supernatural. The show will continue to air in its 9-10 pm Friday time slot come fall. Here's what is coming up next season:

• The Winchesters will find themselves in an increasingly sinister, changing landscape, up against a new foe unlike anything they’ve ever fought.
• They’ll find their old tricks, weapons, and hiding places all rendered useless.
• All they’ll have is each other.  And the certainty that, like the last of the cowboy outlaws, whatever they face, they’re not going down without a fight.

Any thoughts on who the new Big Bad will be? Cthulhu, perhaps?
