It's a good thing Wrestlemania is two days now because looking at all these names I don't see how you realistically fit them all into one night without doing one of those Wrestlemania 32 style never-ending shows. Like that 4 way mixed tag probably has 0% chance of actually happening but it's full of names who are big enough stars they probably have to be on the show somewhere.
