Re: 2015 Will Be The Worst Year in Wrestling History
That's still a long way too go. The Undertaker may surprise people and still have some more Wrestlemania matches left in him after that. CM Punk may change his mind about wanting to retire. And I really don't think the WWE would need to rely on part-timers so much if they built up the talent the full-time talent they have now, so we'll see. They do seem to be taking the Sheild pretty seriously.
As for John Cena, I really do think his time at the top is coming to a end in a few years. Their really isn't much left for him to do at this stage of his career other than chalenge the Undertaker for the streak at Wrestlemania. Also, their is the rare chance of a Cena heel turn, which although I do find unlikely right now, when (if ever) it does happen, I think it would open up a lot of new creative storyline ideas to work with. You could have Cena turn heel at Wrestlemania 31 or 32, then try and build up the next top face for a year or two to defeat him at Wrestlemania 33 or 34. I'm just throwing ideas out, but maybe you get the point.
As others have said, let's wait and see before we start to panic.
