A video promo for SummerSlam has confirmed that John Cena vs Brock Lesnar will be the main event. The video appears to have been a pay per view teaser for MTS.ca/ppv.Obviously the spot was never meant to get out this early, with it effectively undermining this Sunday's WWE Battleground pay per view. Then again, there's no confirmation that Cena will be Champion going into the Lesnar match, so that still leaves this Sunday's main event with some unpredictability. The video is a very compelling sell for why you should watch Cena vs Lesnar this August. It puts over Brock strongly as a former UFC Heavyweight Champion. That's something WWE should have done a lot more of in previous feuds. Lesnar is a legitimate hard man, he sold a millions buys per a show for the UFC with his tough guy status. It's good to see WWE now promoting him as such, rather than the cowardly character they previously booked him as in the WrestleMania 30 run-up. The tagline for the event is "Ultimate Battle" and John Cena is referred to as "The biggest superstar of our time". We also see in bold lettering that Cena is a "15 time World Champion", which could be a clue that the title will indeed be involved. Lesnar's NCAA, UFC, WWE and streak conquering achievements are then pushed hard. The video headlines him as "the most dominant athlete ever." This is really great promoting on WWE's part. It's pitting an immovable object against an irresistible force. That's compelling for buys because fans really can't imagine who could possibly lose. By playing up both Cena and Lesnar's accomplishments, WWE have really strengthened that intrigue. How can Cena overcome the most dominant athlete ever? How can Brock victor over the biggest superstar of our time? WWE are pushing the feud exactly how they should. They've also been smart by putting together the two biggest mainstream names they have under contract. Even outside of wrestling fandom, this feud is going to draw interest. Cena and Lesnar have a degree of semi-celebrity status, putting them together is a great formula for selling pay per views to people who normally don't buy into wrestling.
