with such a big release, shipment will usually need to start 2 working days before release, to ensure all stores have the supply and etailers will normally recieve there stocks a day earlier than that, to turn around the stock for redistribution to customers for release day.
They only release of any kind that Ive worked on, for distribution that didnt happen like that was a Harry potter book, where stocks were held in secure warehousing, till one day before release, when massive amounts of books then had to be moved at great expense, all in one day to be in store for the release next day.
Online etailers recieved their stocks a day before release and had to turn them round the same day for distribution to customers the next day!
This required massive manpower, and a lot of advanced planning to ensure all stocks could be moved an instore for release.
All this was to protect the content from leaking, i dont think GT4 has that kind of worry.
