At this point I'm not confident that Amazon.fr will have enough stock for all orders at launch, especially since they don't seem to have a limit on how many you can order per customer.
I contacted Amazon FR today and they said my order will definitely be arriving on release day. Also, they said that the price should update too, and that there is no need to cancel and re-order.
EDIT: Having a hard time believing that second part. I'm tempted to just cancel and change to the Neon one and get Zelda 'seperately'. It's a €1/€2 difference so....
