Hmmm, what about The Clone Wars? Will Cartoon Network keep the rights to air it?
No reason why not, unless Disney chooses to buy out Cartoon Network's licensing contract. It's hardly unprecedented for a show owned by one corporation to air on a network owned by another -- for instance, Warner Bros.'s Fringe
airing on FOX. There are advantages to having your own corporation's show on your own corporation's network, but it's certainly not mandatory.
