3ds done the same thing and keep in mind it sold SLOW early on and took a few months to take off. It's typical of a Nintendo handheld, not a milestone.
3DS needed a huge price cut in order to sell... but sure... keep ignoring it.
Switch won't fizzle out as quickly as the 3DS either (which constantly under-performed to Nintendo's expectations).
