For a couple of years now, it has been rumoured that WWE want to do an angle of Mr McMahon versus The Authority. The story would be that McMahon picks a wrestler to represent him at WrestleMania against a wrestler of The Authority's choosing. Whatever side loses the match, is removed from WWE. What would be a big way to bring Cena back in December, is if it was advertised in advance (for those all important Raw ratings) that Mr McMahon was going to be on the show with a special announcement. That's instantly big, as McMahon is so rarely on these days. He'd come out and announce he was looking to take the Authority down at Mania, with the aid of a very special weapon... John Cena. The franchise star would then come out and shake hands with McMahon, promising that The Authority's days are numbered.
