Wrestling will be ruled by "vanillia midgets" by that time. We're starting to see it already, the smaller guys will start to take over and the bigger guys will just be sideshow mid carders.
Also someone will cash out and sell WWE. I don't see it continuing to be in the hands of a McMahon or Helmsley...can't give a reason just think it will get sold. On a limb it will be unfortunate but because someone has a freak accident and dies in the ring. Not on some Owen Hart shyt but just some regular having a match, move goes wrong and
Punk will be back and I honestly think it will be within the next year.
Lastly...HBK will wrestle another match... it's going to happen.
