[Soundwave]

45-50 million all things considered would be a reasonably passable.

DS did not have to compete with tablets/smartphones, and 3DS also was able to get by a couple of years before smartphone gaming and cheap tablets accessible to kids exploded.

Even comparing to the 3DS in some ways is unfair, Switch has a much steeper mountain to climb.
