This'll be really short
I have a theory that every 5 years since the year 2000, a new batch of main-eventers are pushed. This lasts around 2 years. For example 2000 was the year of Triple H and Jericho and more people like that. 2005 was the year of Cena, Batista, Edge and Orton
Maybe this year more will be created. Sheamus has already been pushed, and Swagger. Maybe JoMo or Dolph Ziggler, or Kofi? Or Matt?
