No Season 6 for Supernatural?

Well, Season 4's ending was pretty epic, and I can't wait for next season to see what happens. But creator Eric Kripke says he only has another season of story left in him, and both Jared Padalecki (Sam) and Jensen Ackles (Dean) want out when their contracts expire after season 5.

At least, according to this link.
