Somebody at WWE or Amazon most likely jumped the gun and uploaded artwork for the SummerSlam 2014 DVD/Blu-Ray featuring Brock Lesnar and John Cena.
The image was eventually taken down since it pretty much spoiled the outcome of the upcoming Money In The Bank ladder match for the WWE World Heavyweight title but as everything, once it’s on the Internet, it’s there (somewhere) forever.
Lesnar has been long rumored to be winning the title at SummerSlam, keeping it till WrestleMania where the “next big thing” would defeat the man who defeated the Undertaker’s streak.
John Cena vs Brock Lesnar has already been done with Cena going over. The match took place at Extreme Rules following WrestleMania 28, the first match for Brock Lesnar since his departure from WWE in 2004.
Obviously plans can change and Cena winning the WWE title this Sunday is not confirmed by any means.
