Does anyone else think this might happen?

If CM Punk wins the WWE title at MITB and then leaves the WWE maybe it will be a scenario like either Wrestlemania IV or Survivor Series 1998. The title was vacated and there was a 14 man elimination tournament for the title. Randy Savage won the title at Wrestlemania IV and the rock beat mankind for the vacated WWE title at SS. On Raw 6/13/11 CM Punk stated that by giving him the match with John Cena SCSA has just set into motion something that would change the WWE landscape. Could this happen? Maybe the main event at Wrestlemania 28 will be a championship match but with neither the rock or John Cena going in as champ?
