I can see Ricardo Rodriguez just for the simple fact that ADR some what needs him to get the cheap pops from the crowd and when he is full heel, it will be more entertaining. Possibly a Hardy Boys return to amp up the tag division, this is assuming both are clean and in good favor of Vince. I am sure Daniel Bryan will make his return, possibly in the rumble but who knows. Another obvious one is Seth but I really don't need to mention more on that. Maybe one last run from Rey Mysterio but I hope not. He was amazing when he was younger but he messes up too much in the ring now and I don't want another Rey vs ADR feud. Oh and of course, the Rock. Cena will be back before 2016 my guess. He never stays away as long as he says.
