I don´t think that we will see either the creatures from the bad place or the hooded figure. These were used to set up Wayward Sisters and it was too late to incorporate them after the announcement about Wayward.

We might have a new character/creature in Dean.

Maybe time travel. Dean´s new persona could be a person out of time.
