While the general consensus is that Brock Lesnar is about to leave WWE and head to The UFC for his fight against Daniel Cormier especially after losing The WWE Universal Title last night at SummerSlam, the main difference right now is that Vince McMahon is willing to match any giant UFC offer that Lesnar gets. From Lesnar’s perspective, he could easily take the WWE money and work his handful of WWE shows and still come out financially in the same position.
 
Either way, whatever Lesnar decides to do, Dave Meltzer on a recent edition of The Wrestling Observer Newsletter says that he is willing to bet that it will be another short-term deal, maybe six or nine months so that Brock is back in the same position next year leveraging WWE and UFC against each other. Lesnar is smart and knows that both promotions are about to land into a ton of money from their respective TV deals.
