I feel like the nes->snes, gb->gbc->GBA, ds->3ds, and wii->WiiU were all pretty similar advancements.
In all of those except nes->snes you had backwards compatability, and the wii->WiiU had hardware backwards compatibility (which the switch 2 doesn’t, at least for controllers).
Being Nintendo the fact that it is basically the same is the actual surprise.
