if king of the hill didn't get cancelled, do you think it would have after the death of brittany murphy?

u know mike judges king of the hill (also creator of beavis and butthead) right? well do you think they would have cancelled it after brittany murphy died or found a new voice actor? just a little info, brittany murphy died in december 2009 due to pneumonia and poor health. yes the show did get cancelled in 2010, but i think they werent making episodes at the time. they were probably trying to find a new voice over actor until it got cancelled in may 2010. brittany murphy was the voice over actor for the character Luanne.
