Switch should have little trouble finishing the calendar year at 150m shipped, but it would obviously have to be well over that to hit Nintendo's 154.82m projection by next March. I once said that I believe Switch will be just below the DS' total by March 2025 and I still stand by that, since I think it could indeed miss its 13.5m fiscal target.
But it should be clear to anyone by now that Switch is destined to become Nintendo's biggest selling console for sure. It just ain't in the cards that it falls short of that accolade at this point.
