I'm getting the feeling that HBK might super kick Bryan and help Orton to win. Shawn Michaels has a horrible record of calling a match as a referee without there being some sort of controversy involved (Summerslam 1997, an episode of Smackdown in 1999, New Year's Revolution 2005, Wrestlemania 28... Judgment Day 2000 being the only slight exception) and the talk of the dirt sheets is that Orton is supposed to remain in the WWE Title picture until January of next year. Assuming that last part is true, having Michaels turn on Bryan and cost him the title is as feasible way as any to get Orton the win without killing the cell gimmick by having someone (i.e The Shield) break in with bolt cutters (or even worse, have them hiding underneath the ring already when the cell is put down.)
Just picture Bryan charging towards Orton at full speed with the running knee, only to walk right into Sweet Chin Music.
