I’m guessing this is from consumer pressure, until the Switch people definitely bought more physical copies of games and the minority of people got digital versions of DS/Wii-U games, but now so many people are using nintendo online and buying virtual copies people probably would not buy the next console if they had to buy the games they liked again.
