When it could happen - WrestleMania 31 or SummerSlam 2015 Why we can't wait - The top two stars in WWE doing battle, the question of will Cena go heel, a rematch to 2013's classic Dave Meltzer of the Wrestling Observer is reporting that he doesn't expect Cena vs Bryan 2 to take place any time soon, with WWE planning to keep both men apart as the number one and number two babyfaces. However, given that both are vying for the same spot as WWE Champion, it has to be only a matter of time before they do clash again. This is what WWE should always be about, just like Hogan vs Warrior, Michaels vs Hart and Rock vs Austin. There's no better programme than two top guys (with very little between them) doing battle for the WWE championship. It's even more interesting because we know they're legitimately fighting for the top spot in the industry. Cena vs Bryan is arguably the most high stakes match in WWE. What will make the contest a sell is that the first battle, SummerSlam 2013, was so good. You also have the fact WWE could tease (and even possibly do) a John Cena heel turn. The storytelling in that respect could be very engaging, Cena saying that he needs "to win at all costs" after losing 2013's contest. It's a match easily fitting for the main event of WrestleMania 31, top guy versus top guy, just as it should always be in an ideal world.
