Depends what the Japanese Branch does, but it doesn't look good for them either. The great Talents of Iwata's and Miyamoto's generation are now in their late 60s to 70s and looking at retirement, and the next generation have mostly gone off to do their own thing like Sakurai. The result is that leadership is likely to consist of dudes who made it their life goal to climb to the top of a big company, rather than anyone who has any special connection with video games.

I predict a much slower fall where Nintendo starts using its vast war chest to purchase second party developers in an attempt to inject new creativity, before consuming them in the vein of our least favorite American video game companies.

My gut says they stick around in their current form until at least 2035, when they might restructure if the Switch 3 goes poorly. And even then I expect them to pull a Sega and use their vast IP library to make money by sticking Mario or Pikachu's face on every product with a flat surface to draw it on.
