Actually, it could be 3 straight years of Rock/Cena build (Miz was just kind of there).
I think most will be tired of 3 straight Mania seasons revolving around Rock/Cena and their promo/pre-tape well is dry.
I was pretty tired of just 1.... To be fair Rock vs Cena was a good match. Eventually they need to stop with these "x returns to wrestlemania, then leaves" ... They make money but thats not sustainable.
