Supernatural concluded its season with a series of shocking developments, the most prominent of which involves Castiel. Catch up on the finale with our review NOW.

How will those events affect what's ahead? The CW offered a few hints via the following press release, which the network sent out along with its fall schedule:

In season seven, 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.

Who might this "new foe" be? The new God we met on the May 6 episode? Sound off with your thoughts now!
