I'm speculating that by the time John Cena truly begins being phased out there won't be anyone adequately to replace him. Not unlike Sammartino and Hogan before him there was a dry spell as the newly anointed didn't 'quite' get it done. With HHH taking over a new philosophy is being bred behind the scenes. HHH surely recognizes his talent isn't full of Ortons and Batistas. Suppose WWE is heading in a downward spin, that Reigns isn't the anointed. Creative is bad almost by design at this point. If Wyatt continues his rise, organically, he may become what Austin became: the anti-hero nobody could've guessed would draw. With NXT strong and HHH recognizing the necessary change, we may see a boom period, particularly if Reigns becomes the failure I predict he'll be. The bubble gum stuff we see now will have to be phased out.
