You have obviously misunderstood the press information released by Funcom during the past weeks. They shipped 700 000 copies to be available at day 1 (excluding 110000 Collectors edition), not to be sold out on day 1. It is further worth noting that they say nothing about expected sales at all other than that they expect to pass the 1 million mark with this game (i.e. not within a day or week). It is worth noting that the original shipment alone couldn't satisfy the initial demand, but that an additional 300 000 copies were shipped. Even so, in total, the number of boxes shipped (excluding Collectors edition) just recently reached 1 million, so it is quite clear that they did not expect 1 million on day 1. They scaled their servers for 600-700 000 simultaneous users. Finally, these numbers are NOT specific for the US, i.e. the numbers are for Europe and North America (the game is not launched in Asia, Africa and Latin America at all yet).
