That brings us to WrestleMania 40. This one is harder to predict. Just like you never would've predicted Daniel Bryan closing WrestleMania 30, it's pretty hard to say who'll be headlining by WrestleMania 40. We have a pretty good idea of the next generation of stars who will work the 30's, but upon Mania 40, surely a new star will be on the scene. This person is probably not even with the company yet. This is where WWE's investment in the Performance Centre and NXT division pays off. Whoever will be headlining in ten years time, they will be a bonafide WWE creation. WrestleMania's future will then revolve around the wave of talent coming off the production line down in Florida. That's why the Performance Centre is worth every dollar of investment, it will open up opportunities for people to 'be the man' in WWE's future. Our prediction for Mania 40 is a main event between two men who aren't even past their teens yet. They might still be in school, it could even be someone reading this very article. The next ten years will be dominated by Roman Reigns, but at WrestleMania 40, it'll be the turn of a new generation. The 'Performance Centre Era' will officially blossom ten years from now.
