Season 15 is the last season under the current contract. It is up to Comedy Central to extend the contract. And if they don't, another network may pick up the show. So it is not certain at all that season 15 is the last season, but it is possible. Nothing lasts forever, and maybe Parker and Stone want to do something else, you never know.
