Iwata was committed to maintaining the core set of business philosophies set by Hiroshi Yamauchi. Once Iwata was gone, Nintendo's new leadership decided to go a different direction.
Currently, they still have the IPs that everyone knows and loves from previous eras, but the core philosophies that pushed the company to multiple creative and financial peaks is different now. I don't think it will happen overnight, but they're probably going to adopt a lot of modern conventions that the old guard never would have allowed. Mobile and PC gaming, for example. They'll have some flash in the pan success as people are excited by the novelty of Nintendo doing such things. Mario Kart on Steam? Big deal for a while, and then eventually they'll be just another publisher.
