Market analysts NPD have suggested that the Xbox 360 was the best-selling console in the US over Christmas - with the Nintendo Wii trailing by just 200,000 units.
According to the firm's preliminary estimates, as reported by CNBC, around 2 million Xbox 360 units were sold in North America from November up until December 25.
The figure for Nintendo Wii stood at 1.8 million units - despite the fact the console only launched in North America on November 19, and the first batch of stock sold out within hours.
Stock shortages were an even bigger problem for Sony. Around 750,000 PlayStation 3 units were sold during the same period.
NPD is expected to release complete figures later this month.
