The source isn't that trustworthy for me, but still:
"Initial numbers for sale quantities of the Halo 3 video-game from Microsoft are coming in from a number of sources. The Xbox 360 exclusive title is said to have sold through 1.8 million copies during the first 8 hours of release. This quantity breaks down to about 1.5 million units sold through pre-orders, and additional 300,000 copies sold at impulse (without pre-order).
It is estimated (assuming this trend continues) that a total of 950,000 fresh units will be sold within the first 24 hours, bringing the grand total to 2.45 million units (950,000 + 1,500,000)."
