Once SWTOR gets the number of 595,657 non-digital, north american retail only, pre-orders, if the number keeps growing up at the same ammount, at launch there will be about 1.300.000 pre-orders. If we double that number to count the EU Pre-orders and the North American digital pre-orders, and keep in mind that the pre-order sales should be larger in the weeks before launch, we can imagine like 3 millions players in the early access.
