That is like the most common question when will Cena turn heel?! I have come to the conclusion that when Cena turns heel we wont expect it. It wont be the dirtsheets. The IWC wont know it's coming. I do believe that if they want Cena vs Taker at WM 28 would be without a doubt have Cena be heel. There is mixed emotions about that. Which I can understand. There is a lot of young talent out there and upcoming that Cena can easily fued with and put them over. But I would like to see (As faces) JOMO, ADR, Sin Cara, Daniel Bryan, Ziggler vs (heel) Cena. There are a lot more that would be great. But from the top of my head i believe those will be worthy.
