If you check into the FOX website for King of the Hill, go to the very bottom of the episode guide. Believe it or not, there's going to be an episode coming called, "Leanne's Saga"! Not Luanne's Saga, BTW.
Who is Leanne? Could it be Luanne's mother perhaps? Also, there's an upcoming episode called, "The Final Shinsult", too.

P.S. I hope they show a new episode next Sunday! :)
