What comes after


Ok Scott I get why WWE is trying to draw interest in the WrestleMania main event by making it a winner takes all unification match. My question is what happens after WrestleMania? Does the champion show up on both shows from now on? Maybe the brand split ends? Or maybe the champion loses one of his belts at Backlash ala Becky Lynch in 2019 making the unification useless in the long run. Your thoughts?
I bet they just strip the winner of one title and do a series of Beat the Clock matches on Raw to qualify for a pair of ladder matches on Smackdown where the winners meet each other in a arm wrestling match at Wrestlemania Backlash: The Horror Show In Jeddah IV (Night 3) to determine the new champion.
