Exactly, I think of it more like this: The new guy assumes the mantle of Iron Man but Tony catches on. After a deep thought he decides not to remove the armor but instead become a mentor of sorts to the young hero (assuming he's young) so he can properly take the mantle and become the "official" Iron Man while Tony becomes sort of a tech support member for the Avengers and his company (like Steve Rogers did while Bucky was Cap)
