This is not what Nintendo claims on their website

Sign in with your Nintendo Account and register your interest in purchasing a Nintendo Switch™ 2 system and select accessories from the official My Nintendo Store. We’ll be in touch with an invitation email once it’s your turn to shop.

Open to Nintendo Account holders in the U.S. and Canada, who are at least 18 years old. If you are eligible, an invitation email will be sent to the email address associated with your Nintendo Account when it is your time to purchase. The invitation will be valid for 72 hours. Invitation emails will be prioritized on a first-come, first-served basis to registrants who have purchased a Nintendo Switch Online membership with a minimum of 12 months of paid membership and a minimum of 50 total gameplay hours, as of April 2, 2025. Once invitation emails have been sent to all registrants meeting the priority criteria, invitations will be sent to remaining eligible registrants on a first-come, first-served basis.

Invitations are non-transferable and will be sent to the email address associated with the Nintendo Account that registered interest in purchasing Nintendo Switch 2. Optional accessories will be available to purchase alongside your system. For system and each accessory, limit one purchase per eligible Nintendo Account during the invitation period.

So it looks like you need a Nintendo account (obviously), be at least 18yo, have purchased a Nintendo Switch Online membership (minimum 12 months), and have 50hrs total gameplay as of today. I don't know if that gameplay is 50hrs total or online only. It's first come first serve. ~~The title is misleading~~. The requirements are different in the UK.
