in my opinion it will be whatever airport is cheaper to operate out of. covered hangar space would likely be sought after also, due to the winters.
we also know Barry (smartly...) does not re-invent the wheel. If a few airlines had hubs or heavy presence there, and stream of passengers, it is attractive as a base. McDonalds across the street from Burger King 101 stuff. Every pilot base so far (now closed ORD in the list) has been a Big-3 hub, Big-3 crew base, or Big-3 major presence.
CLE has more of that than CVG but who knows what the crystal ball says.
