Great discussion! I am getting excited by the possibilities. I hope Cena turns heel but the way he is currently the top face (even over Orton), I don't see it happening. I bet Orton is one of those reluctant faces backstage just like Carlito. Hes just a natural heel and you can see it in him that he doesn't feel completely comfortable being face. He can't be the only top face, therefore I say Cena won't turn. Hope im wrong though!!
I would also like to see Miz cash in the MITB on Orton after beating Barrett or on Barrett after beating Orton. Either way, I think hes ready.
It would be interesting to see Barrett as champion. I also think hes ready as well. Hes great on the mic, hes a great on screen leader for the Nexus and it would be a great way to see the group continue onward and being legitimate. If Barrett loses, then I don't really see anything major for the group to do cause that would mean he failed twice to win the title. It would not even be interesting to see him get another shot. Barrett has to do it now or fall into obscurity for a few months. Nexus with the WWE title and the unified tag titles would show me that WWE is still trying to push them as serious contenders among the WWE rankings. I can see it happening.
Any other the above i'd like to see lol.
