A few customers have brought to our attention the way we allocate backordered items. The mode of backorder fulfillment was to deliver based on RED ONE serial number. However, we agree with customer feedback and think it should be based on delivery date of the RED ONE. If people have the same delivery date, serial number will be the secondary sort. And to clear up any confusion, RED will consider the date your order was invoiced as the "delivery date" so not to punish our international customers for taking a few days longer to take delivery than our domestic customers :)
Simply put, order of delivery date of the camera is the right way to go.
