I was going to suggest Darkwing Duck but something that sounds this big suggests to me something like an Aladdin play set with Genie and Jafar as the last two Disney Original figures to be announced.
Of course that would mean Aladdin and Jasmine toy box pack upgrading to a play set pack but after the recent Yondu development this would be extraordinary if true!
But we can only hope its that good what playset would you go for if it involved ALL of the Disney Original figures?
