I honestly predict a bit of a clusterfuck ending especially considered that both belts will be hung up. This means that both belts can be disloged by individual superstar. What happens when only one of the belts is pulled down? Does that mean they have to continue the match to get the other one? So this means the entire first half of the match will either be them trying to get the WHC first, or neglecting it entirely and just grabbing the WWE title.
Should be entertaining just to see how they actually go about a match that has two belts and two competitors called a unification match.
