Thinking about it, I actually hope he interferes in the title match and costs Bryan the title. Although it would initially enrage fans to not see Bryan win, we would possibly get a long program with Bryan and a heel Punk. It makes sense for Punk, that he was tired and jealous of the adoration for Bryan despite him being a great worker too, so left the business.
But it means that we end up with Orton or Batista as champ. Pity there is no current money in the bank holder...
