Looking at what Nintendo has done in the past has some value, but I would be cautious about saying "well that's how things were done in the past, so automatically that's how things are done now".
Nintendo of today is a very different company from even 10 years ago, the board of directors is very different. Nintendo of even 10 years ago would not be making smartphone games, theme parks, paid DLC, paid online, using an off the shelf Nvidia GPU, etc. etc. It's clear current Nintendo embraces multiple revenue streams and the whole "well Miyamoto doesn't like CDs/online/smartphone games, so we're not going to do it" philosophy has gone out the window.
They're not nearly as dogmatic about stuff anymore, if something makes them money, they more often than not will do it.
