Nintendo fans are not joking around with the Nintendo Switch since it may be the Wii launch all over again with no systems around after launch. According to NeoGAF user, ultrazilla Gamestop will put you on a list to pre-order the Switch.
He pulled out a piece of paper and said put my name and phone number down(I was number 7 on the list) and when they hear from corporate about official pre-order details, they will call us in order on the list to see what is required(probably just simply moving our names in order to the official pre-order list).
Every Gamestop maybe different as all managers like to do things their way and try to be fair. If you are dying for a Nintendo Switch I would go to your Gamestop very soon to ask about this.
Good luck and have fun
