WWE would be silly to let him go with the huge following he's created for himself. They know that as much as we do. They will accommodate his needs and most likely give him as much time as he wants.
The only way Punk is leaving the WWE is if he quits. He won't ever be fired.
"Huge following"
Where were they while he was WWE Champ and drawing record low ratings? I hate to have to keep interrupting these CM Punk threads but they are constantly filled with exaggerated posts like this.
Punk has a niche following based around internet smarks, who don't pay for PPV's and constantly whinge about guys not getting pushed. WWE isn't exactly missing out on much if those fans get disinterested.
