Xbox Europe boss Chris Lewis has told MCV that "Christmas" 360 sales were up 120 percent at the end of last year.
"Christmas 2008 was the biggest sales period in the history of the Xbox brand," he said.
"Sales of the console were more than double over the period a year before, in excess of 120 percent in fact.
"We've had record sales in January too – much better than we anticipated. We're at over 8 million console sales to end of 2008."
