Check your emails if you’re a My Nintendo member as select people are receiving invites to test out the Nintendo Switch early. Details are scarce but the message says the following: Dear My Nintendo member, To thank you for being a loyal fan, we’d like to offer you a chance to try the Nintendo Switch system before it’s released. Look for an email from Eventbrite for the full details and be sure to register right away to save your spot (availability of tickets are on a first come, first served basis). Go check your email now!
Thanks to geelw for the tip.
