8. A Cena Heel Turn
An ultra bold move on WWE's part would be to turn John Cena heel at Hell In A Cell, then have him walk out of the WWE. The way it would be booked, is Cena losing the US Title to Ziggler. The crowd would undoubtedly pop for Ziggler's win and he'd be the babyface of the situation. In the post-match, Cena would take a mic and be a sore loser, finally snapping at the crowd after years of negative reactions. "You chant John Cena sucks... well, screw you guys, I'm outta here, I'm done with this, see how you like WWE without me!" he'd blast before walking out. That then sets the scene for a return in December, when he'd come back as a full blown heel for a WrestleMania feud with The Undertaker.
