Do you think South Park is over?

Last nights ending was one of the most depressing episode in the history of south park. (Other then the episodes were the little 6 year old dies of cancer and the one were kenny dies for good) And the episode was hinting that the show is done for. In a way i will be a upset to see the show go but i think it is almost time for trey and matt to take a bow for years of entertainment, the show has been loosing the fire it has had, there still are a few new newer episodes that i think are VERY good and have a great plot to them but if trey and matt can not make any new ides and have to resort to racist jokes and over used material i think it is time to stop, and its like a great man one said... "All good things must come to and end".
