According to Xbox Evolved, GameStop officials have confirmed that pre-orders for Halo 3 have already passed the 4 million mark. If true, this would make Halo 3 the most pre-ordered game of all time (unless GTAIV catches up). Assuming most of those pre-orders are actually purchased, it also puts Halo 3 in the running for first day sales records (which isn't exactly surprising). Keep in mind, these numbers are only for GameStop and its affiliated stores. Throw in other retailers and the number of pre-orders must be staggering.Our big question: how many of those pre-orders are for the Legendary Edition?
