Nearly all of them.
Of the internal EPD teams, EPD 3, 4, 5 and 10 have all done multiple games for the Switch.
Of the other teams they own, MonolithSoft, Next Level Games, and ND Cube also delivered multiple Switch games.
And then for external partners, Intelligent Systems, Platinum Games, HAL, Camelot, Gamefreak and Bandai Namco Studios delivered multiple Switch games too.
So basically I don't think anything is going on at Nintendo overall. They tend to publish 10 or more games a year, so they have a good output.
Obviously something was wrong at Retro, and potentially something went wrong at EPD8 too. EPD9 was wasted on Mario Kart Tour, which might not have been the best use of them.
