In Japan, Nintendo Switch 2 launch title Mario Kart World has sold more physical copies in the first three days on sale than Switch 1 launch title The Legend of Zelda: Breath of the Wild managed in its first three days.

You can't simply go to the My Nintendo Store and buy the Switch 2. To order the Switch 2, you need to log in with an active, paid Nintendo Switch Online account. Once you do that, you can choose either a Switch 2 standalone console or the Mario Kart World bundle and then hit the confirm button to "register your interest" in ordering a Switch 2.
