To add to this, I'd say that there's likely a good amount of creators who want their characters to outlive them. Look at Spawn; Todd McFarelene (however you spell his name) has overseen the comic in a producer type capacity but hasn't been hands on for ages (though I guess he's gone back now?) And I suspect that Mignolia (spelling?) would be quite happy to know that Hellboy was going to continue after his work is done. What artist doesnt want his work to outlive him, after all? I'd think the biggest difference between creator owned work and the guys who do work for hire is that the creator owned folks are more invested in making sure the right people take over for them, as opposed to the work for hire guys where its all just corporate profit mongering.
