I mean, didn't Nintendo literally say in the January reveal that the Switch was like a combination of just about every crossover they've made before with consoles and handhelds? It might not have been them, but I seem to remember it quite clearly. In particular they mentioned Gamecube's handle alongside stuff like the Super Game Boy.
Yes they did. But I mention handhelds specifically because Nintendo's handhelds were getting closer and closer to the design and production values of their console games over the years, especially once they pulled out of the arms race on the console front, which culminated into the hybrid concept of the Switch.
