If I may put on my fantasy booking hat.........Cena beats Punk at SS with Huntor-ference and becomes the corporate champion, thus turning heel. They won't do it, but it's the way I would go.
Punk, since he lost by shenanigans, is not diminished and proceeds to chase Cena until Royal Rumble. At this point, to counteract HHH, aligns himself with someone like a returning Mick Foley, and takes the belt off of Cena at Rumble.
Cena goes onto the build for his Rock WM match without the belt, which is completely necessary. Cena can't have the belt going into that match because we know Rock isn't full-time, thus can't realistically win the title, and you damn sure can't make a WM match non-title.
That leaves Punk with the title going into Mania where he would face HHH to complete the Austin/McMahon style storyline. Hopefully Huntor would put Punk over, forever solidifying Punk into the stratosphere where he belongs.
Now I know WWE won't do anything like that, but as a fan, that's what would interest me.
