first day : 106 servers including EU, capacity estimate around 3000 = around 200,000 to 300,000 players were accepted. amount of per-orders near 1.5 mill These numbers are not completely accurate, and this is purely speculation. However, the amount of servers are correct, and the capacity is a mirror number of wow server capacity. every servers was nearly all high/full for awhile which is safe to assume they let in as much as they could without over doing it.
