I mean, it's neat if Butch goes back to CN but he can't turn the channel around by himself. Yeah he's apart of the original golden age crew of CN but all the other members probably won't ever return
Seth Macfarlane is too busy with Fox to return.
Craig McCracken works for Disney now
Genndy Tartakovsky is back working at Sony Pictures
The only who might can return is David Feiss but all the creative geniuses that made CN great in the first place are long gone
