My Nostradamus prediction:
I can smell a WWE World Heavyweight Championship winning for Brock Lesnar at SummerSlam and a The Rock vs. Brock Lesnar main event at WrestleMania XXXI. Both men are the Biggest Tickets Sellers right now thanks to their crossover mainstream media celebrity status. Which is Great for Bu$ine$$.
However both men are part-timers in the WWE. So the winner of the WrestleMania main event will probably get rid of the title soon after the Greatest Extravaganza Of Sport Entertainment.
Yes I know. It's make a lot of sense.
