Plus the fact that Nintendo's never been shy about iterative console updates: NES > SNES, GB > GBC > GBA, DS > 3DS > New3DS. And arguably Wii > Wii U, and then the Wii U was sort of the missing link between the Wii and the Switch.
Historically they haven't been great at the marketing/positioning around those iterative updates, but maybe this time they've finally learned :P
