Microsoft has announced that the highly anticipated Halo 3 has passed the 1 million pre-orders milestone in North America shattering many previous records, and is set to break Halo 2's first day sales record of $125 million.

"What we've experienced is nothing short of phenomenal," said Bob McKenzie, senior vice president of merchandising at GameStop Corp. "'Halo 3 has eclipsed many previous records and will prove to be one of the must-have items of 2007."
The game will be available in 3 different flavors: a Standard Edition, a Limited Edition and the Legendary Edition which comes with a helmet of the game's main character Master Chief. Microsoft says that demand has been so strong for the Legendary Edition, that they expect it to sell out by the time the game launches.

With Rockstar's GTA IV out of the picture, Halo 3 is easily poised to be the top seller for the Xbox 360 this holiday season. Additionally, huge promotional campaigns with leading consumer brands, including Mountain Dew, 7-Eleven, Pontiac, Comcast and Burger King will begin later this month to promote the upcoming September 25 launch.
