According to early retailer reports, and user polls, Gears of War 2 is shaping up to be one of the biggest Xbox 360 titles to date, putting it in very similar territory to blockbusters 'Halo 3' and 'Grand Theft Auto IV'
Using the aforementioned data, Gears of War 2 looks to have debuted to midnight and Friday sales of 1,400,000 units in North America, and 700,000 units in 'Others' territories. This would represent about two thirds of Halo 3's massive debut, which wound up with 3.8 million units sold it's first week on the market.
Due to the US Election taking place on the 4th November, the release date for Gears 2 was moved back to Friday the 7th meaning that "week one" sales will be made up of two days sales - expected to come in at around 2.5 million worldwide. The implication of this is that week two sales should show a lower than normal dropoff so it is entirely possible that the game may hit 3.5 million sold by the end of week two - in just nine days.
As you can see, Gears of War 2 is shaping up to be a formidable competitor in the November NPD data, and looks to eclipse Gears of War 1 worldwide sales by the end of the year (which is at 5.2 million units).
