crackpot theory: nintendo has been reinventing all of these beloved game series so that they can remake the original super smash bros with all-new movesets based on those reinvents. mario is going to have cappy, link will have his powers from tears of the kingdom and maybe breath of the wild, DK will have tons of moves from bananza, etc.
over the next year we will see each character from that original smash 64 get reinvented in their game in some way and then we'll get a smash 64 remake.
