It's being reported that WWE officials are not happy that C.M. Punk's situation with the company has been made public and that so many details have been leaked out. They were hoping to keep it a relatively private issue between themselves and Punk while they try to work it out.
It's also being reported that WWE Chairman & CEO Mr. Vince McMahon is handling the situation personally and doesn't even want his son-in-law, WWE COO Triple H, to be heavily involved in it. McMahon wants Punk to stay with the company, while Triple H apparently has mixed feelings about Punk staying.
Punk's exit has definitely caused a situation within WWE creative. They are trying to come up with plans for Punk if he returns and they are also trying to decide what they want to do if he doesn't return.
Regarding WrestleMania 30, it's now being reported that the only match that is fairly certain is John Cena vs. Bray Wyatt.
