It's one of the reasons that I've love for Disney to buy Nintendo: they'd actually get the most out of their franchises, rather than letting Nintendo squander them.
I differ on that view, as I see Disney a lot like Nintendo. They have a lot of IP, but I don't see Disney overly using their past IP's. We aren't seeing any new Cinderella movies, more Lady&Tramps, barely any Mickey, Goofy or other original characters coming out into new movies and games. Seems like it's been a long time since anything Alladin came out too. They take their most popular franchises and sell the heck out of them, but once they've lost some appeal they get put on the back burner to make room for their new projects.
I'm sure Nintendo will come out with another Star Fox game or Metroid at some point, but it won't become an annual franchise, even if Disney bought them out.
