Although it could be very long into the future, Cena will have to turn heel eventually. According to that inside report posted, Cena would "love" to turn heel and feels restricted but can't because there is no suitable replacement. When that day finally does happen, and Cena finally turns heel, how do you think the reaction will be?
You reckon it will be anything like this?
Shit went crazy when Hogan turned. I reckon there will be a similar response, would be even more awesome if things get a little more edgy when the day finally happens.
