It will be a huge blow to the WWE if he does leave but they are in no way at fault if he does. He's the one who failed drug test after drug test that kept him away from the title for so long. He was lucky that the E took him back and even more fortunate that they had just enough faith to book him as champ for a month and I think that was more of a thank you for moving truckloads of merchandise just like they did for Rey in 2006. Hardy is also far from the sharpest knife in the drawer, dude's mental acumen could barely cut butter. Remember when he first left the E in favor of drug addiction and "art"? How well did that work out? I truly hope he is leaving for his own good than his own deviancy and once his money burns out he'll be back.
