We will see Roni Regina for sure, because of promo pics and well.... logic

We don't know yet, but it's a safe bet Regina Mills will also appear

What we don't know is if the W!EvilQueen will appear or not. Fans think she will, because the Evil Queen's carriage was in Storybrooke Which picture are you looking a for the Serum Queen theory?

In the case of WishQueen, it's probably easier to explain-away her not appearing that she's dead. Saves using old makeup on Lana. Though it would be cool if they bumped into her in the Wish Realm.
