Honestly, this whole situation with Nintendo and Smash fans is kind of a capitalist wet dream.
Nintendo have a lucritive IP they use to advertise new games while creating very few new characters or locations - but treat its fans with little respect, specifically a sizable subgroup that's more than willing to try something new under the promise of being, and would make them a lot of money if, treated well, and at that a subgroup that's kinda required to buy all the DLC on basis of the way they play.
Unless you've got a Disney-esque brand image, there is no way any media conglomerate would pass on this.
