7. Brock Lesnar Becomes WWE Champion... Or Cena Remains Champion?
Alternatively, maybe there's no angle at all connected to the WWE main event. Maybe Brock Lesnar just does exactly what he said he'll do, kick John Cena's a** and become WWE Champion. That in itself will be a shock. It will leave viewers with an absolute ton of questions. How can a part timer be WWE champion? Will Lesnar be taking up a full time schedule? It's one of the most interesting and more probable shocks that really could happen this Sunday. Seeing Lesnar with the belt will be an image that burns into all of our minds. On the flip side, part of us will also be shocked to see Cena walk out Champion this Sunday. How can WWE possibly give Lesnar the victory over Undertaker, only to then job him out to John Cena? That's why this match is such a great main event. Either result seems unimaginable. Both outcomes will be a shock. That makes SummerSlam a must-watch show.
