did they have a source listed?
anyway, if it is true, I'd be all for heel Cena if it means Freestyle raps again.
Cena would be the face. Turning your #1 face who actually makes an impact for a change, against someone who is better as a heel anyways would be stupid. WWE wouldn't turn Cena when it was practically the only option, why turn him when he's tremendously over and making money?
I know they wouldn't do that, I'm speaking hypothetically...in other words, the idea stinks...
