With the War of the World being nigh, I still think the Shedim will be released, but on purpose, to fight against the invaders. Likely the monsters from The Bad Place as well.
Jack might be able to restore the angels' wings as well, but I don't think he can make more. If he can, however, I presume they won't have broken wings like the others.
S14 will probably involve hunting down the Shedim and the monsters from The Bad Place.
