I've been wondering what Star Wars costumes they might have, and I think Luke's dark outfit and his orange fighter pilot suit is probable, as well an an older Obi-Wan. Leia has a lot of outfit options, but her Hoth outfit or one/both of her outfits from Endor would be nice.
I hope this classic Mickey leads to more costume changes, for Steamboat Mickey, Brave Little Tailor Mickey, and even the tuxedo he wears in the Parks.
