First, it's not really a pre-order as much as it is help with moving large amounts according to last AMA. I think the way people are taking it in spite of that is what's hurting the voucher prices, when instead if people bought/sold/traded with their heads instead of their emotions the pre-sale voucher price would be going up rather than down as these vouchers were harder to obtain than the next phase will be, making them more valuable.

IGN is same.
