Well in season seven (discluding season 6 holdovers), Bunifa appeared for the first time about 20 episodes into the season or something like that so you never know. I could see them ending Fightin' Ron/ Tow Truck Guy because of too many McDonald characters but keeping Rusty because he's classic. I thought I read somewhere he was going to interview Bon Jovi? Maybe they cut that sketch. Walter and Amber were just annoying and know one seemed to know who they were. The Drama Queen I think is done because there's nothing too appealing to last more than a season about her. As for Mickey, he will probably make his annual appearance later this year if he's not cut yet.
