While it's nothing new to fans who have paid attention to the company for the last several years, things are pretty hectic backstage in WWE right now when it comes to plans for Wrestlemania 30. The only match considered to be a lock right now is the one featuring Bray Wyatt and John Cena.
Rumor has it that Bray Wyatt has earned the trust of WWE officials backstage to the point where he is now being allowed to write his own promos. He still needs approval from the creative department before using them on Monday Night Raw and Smackdown, though.
Bray Wyatt has a lot of fans backstage in WWE, so the belief is that he has a very good chance of being put over at Wrestlemania 30 by John Cena. Management really wants him to become a main event performer, and a win of such magnitude would give him the required credibility.
