It looks like Punk quitting was not storyline. A number of fans had pro-Punk signs confiscated on Monday, several who were starting Punk chants were escorted out. The WWE had to cut the audience mikes several times to avoid the chants coming across on TV. F4W reports WWE merchandising companies were told to pull all Punk related merchandise and replace it with Randy Orton products instead.
F4W also reports that the entire WM card is under reevaluation, so far the only guaranteed match is Cena vs Bray Wyatt,
Possible spoiler: there's a lot of talk that the main event will be Batista vs. Bryan, with Batista potentially winning the title at elimination chamber - he'll get into the chamber by injuring Christian.
