I would say the only one to have any real impact in the future would be Mal, since she is Lily's Mom and Regina's friend. Besides, we have already been told we will see more of Lily, so that increases the chances of having Mal step in for an episode. Kristen has another show (I haven't heard if the show was actually picked up yet), so may have scheduleing conflicts to work around. Isaac's story is done with the passing of the Author Mantle to Henry. and Ursula could appear in the future, but again, her story is finished. We might see her at Emma and Killian's wedding (if that ever occurs).
