WrestleMania twenty seven? If he ME's a Mania, it will be way before that. Gone are the days that people will have a good long push to the main events, people were saying Randy Orton will win the world title about 2009, and things of that nature.
If people are good, these days they'll just be pushed before they're ready. Batista comes to mind. (not about the 'ready' bit, that's another story, more about the being pushed to the main's before even a few years.)
