Last time I had an interest in Orton was back when he had his feud with Christian, even then he was miles off his feud with Cena/HHH a few years back. But he could be a great heel again, who against though? I don't know.
One thing I will say though is I have no interest really in the mania 6 man tag match, I'm pretty sure it'll be something along the lines of a the team johnny vs team teddy match last year. Quick match, and just a way of fitting some top superstars into wrestlemania.
