#1 CM Punk joins the Authority
With all of the NXT vs Main Roster stuff going on it seems obvious that CM Punk would align himself with the yellow brand given his previous disposition of leading NXT stars against the main roster.
But what if WWE shocked everyone by introducing a new facet of CM Punk, corporate Punk, and had him align with Vince McMahon and Stephanie McMahon to help keep Triple H's NXT Superstars in their place.
It would be a shocking moment to see the NXT Men's team on the verge of defeating the SmackDown and RAW teams when CM Punk makes his return, in his hometown of Chicago, and in a major swerve, costs them the match.
This also works in a way because it doesn't have to mean that Punk is returning to the ring, he could just be an onscreen figure who appears every now and then to do the McMahon's bidding.
