Just going on past experience with these. Remember when you place the order through Apple, they don't hit your card. You'd be surprised how many people order stuff they can't pay for and the order gets cancelled. Don't know why it's so common, but I used to work in a job years ago where I dealt with card transactions, and people would order something and then their card would get declined, and we'd send it to sales to contact them and they'd end up saying they thought they'd have the money but don't... or they just ordered it hoping they'd get the money, etc... weird weird weird, but hey, Americans love their debt.... I wouldn't be surprised if as many as 10-20% of pre-orders are cancelled\payment decline\changed mind for whatever reason.
