Today, Microsoft trumpeted Halo 3 preorder figures for the first time–and while still impressive, they were a fraction of the previously rumored amount. As of this week, one million preorders of Bungie’s sci-fi shooter have been made in North America–enough to make it the “fastest-selling video game preorder” in the territory’s history. The figure means that the Halo 3 launch could potentially be bigger than that of Halo 2. The then-Xbox-exclusive sold 2.38 million units in the US and Canada in the 24 hours after went on sale on November 16, 2004, generating an estimated $125 million.
