Nintendo is extremely conservative fiscally and will have no trouble surviving purely from a corporation point of view. In my opinion, their largest threat is a new generation that does not know who their characters are. Mario has a ridiculous level of nostalgia for me as someone in his early 30's, but who knows if my son will have anything close to that. Disney solved this problem through a literally awe-some multi-channel strategy combining movies, both new and re-releases on latest platforms, theme parks, video games, TV shows, toys, etc. My nieces are very familiar with Cinderella and Snow White, who is as old as my grandma, but their brother probably doesn't know who Yoshi is. I think the trick is to ride the generational wave. Again, something Disney excels at. A young mother takes her daughter to see the live-action Cinderella movie because of the nostalgia she has for the character, which she in turn got when her mother bought the VHS for her because of the nostalgia she had from seeing it in the theater as a little girl... There is a limited window of opportunity that Nintendo has. Personally I would love to share Mario, Yoshi, Donkey Kong, Link, etc. experiences with my son vs. random new IPs that mean nothing to me. Speaking of Disney, the Nintendo catalogue is one of the few remaining significant cast of characters not owned by Disney. If Nintendo does hit dire straits and I were Disney, I would aggressively try to bring them into the fold, although it is extremely unlikely Nintendo would capitulate.
