For those that are interested, a preorder book is a quantity listing of retailer preorders outside of the standard first distribution shipment.
For example, game company A will order 500,000 units as initial shipment, usually more than 6 weeks before launch date. These numbers are marked as inventory for sale only from this particular date. As the game approaches launch, preorders increase, which will require inventory stock from this shipment to cover when it lands. When this inventory stock is preordered heavily, the amount available for the sales period become too low. As a result, a pre-order book is done to allow for these extra orders, outside of this first initial shipment.
Mr Reeves has thus stated that retail preorders worldwide (presumably) now exceed 1.1 mill. If it was Europe only, Sony would be screaming it from the rooftops.
It does not represent initial shipment numbers.
