I called their Digital Library customer support to ask if we will be able to preload the game. Their "codemaster" said that it depends if Nintendo gives them the codes early. If they do get them, then yes we can preload, as that is a service BestBuy highlights for reasons to purchase digital. However, it is case by case per title. So they recommended to call them again closer to the launch (the week of, or a few days before) to see if they will get the Nintendo codes in time.
