This feels like a very natural progression to me, I really don’t see a problem with it as long as they continue to make sure their games are the core of the model and use other media as supplemental ways to build up brand and character awareness. I think anyone would agree that some types of stories are better told via games and others via movies, shows, or books. Broadening their scope allows for more stories to be told.
And theme parks or things of that nature are just cool ways for people to tangibly experience Nintendo IP.
