Microsoft's Major Nelson reveals that Gears of War 2 sold two million copies after its emergence at retail last Friday. More than 1.5 million people signed into the game over the weekend, helping it achieve a new record for concurrent players on Xbox Live.

The Major's post doesn't distinguish if the two million figure is global or just US. Microsoft may send out a more detailed press release later touting its achievement (bleep bloop) when the West Coast goes to work. We'll update if there's any extra information.
