The New Day appeared in a video on TMZ, which you can watch below, and announced that they will be "The Hosts" of WrestleMania 33.
This presumably means they will not be in the title picture for the Raw Tag Team Championships, and also that neither Big E, Kofi Kingston, nor Xavier Woods will be on the card in any capacity. A spot in the Andre The Giant Memorial Battle Royal is unlikely.
"Our main goal is to have as much fun as possible because if were having fun, everybody's having fun," said Kingston.
They will join a list of past hosts of WrestleMania that includes The Rock, John Cena, and Kim Kardashian.
