As much as i like The Rock & was really looking forward to him versus Cena, in a year from now i predict i won't really care anymore, the excitement that has been around for the last couple of months with Rocky returning and the deal with Cena was great having to wait a year for the payoff not so much. to me it means the next year in Cena's career and/or w/e The Rock does in the WWE during that time frame won't make much sense, because everyone knows it's Cena/Rock next year.
btw i'm with cowboy's prediction on this one too.
