I think Amazon has a good feel for logistics.
"Hello,
We're contacting you about order # for Super NES Classic.
We recently learned that we may miss your delivery promise and apologize for the inconvenience. You will still receive your order of Super NES Classic. We are working hard to ensure you get this item as soon as it is in stock. You can track the status of, or make any changes to, your order under Your Orders on Amazon.com."
I got one a minute ago
Glad I got an in-store Gamestop preorder
oh you sweet, summer child
"you get 500k PS5!"
I got my preorder in within seconds of it going live so If I'm not okay then no one is lol
I preordered as soon as the Wario64 link went up and I got the email.
Sorry but they actually aren't this good at predicting launch deliveries for a sold out console this early. consoles come back in stock over and over and there is zero chance that even if they somehow know they won't get another allotment from Sony (unlikely that they won't as Sony gets a sense of exact units being readied) they are predicting they will need every order they got and more after cancellations already. They just don't know all that yet.
While I hope they can get through to everyone on Day 1, in case they can't I hope they go this route. I got in during the first wave.
