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.

Demand for the Nintendo Switch 2 was evident Wednesday night, as social media users posted photos and dispatches from outside Seattle’s only Best Buy store.
