Well that's not good news... courts in several nations have ruled that Nintendo doesn't have to allow the cancelling of pre-orders and can keep all of the money even if someone wants to cancel the order before the game is released.
Let that be a lesson to everyone: only pre-order from places that will give you a full refund if ever you want to cancel, and if you want to retain your maximal legal rights, always order tangible copies of software that you can use offline for as long as you want instead of buying (read: indefinitely leasing) purely digital products that you have no control over whatsoever.
Talk about anti-consumer!
