2. John Cena's Miraculous Return
How about Cena still being injured being a work? Maybe the real plan is to have Ryback injured prior to the match and replace him with John Cena? This way WWE gets to avoid the difficult decision of whether to take the belt off Punk/end the streak and instead go with another Punk/Cena battle. I think we'd all rather see that match at this point, wouldn't we?
