After the most recent NPD figures showed strong US sales for the PlayStation 4 in January, Sony has provided an update on the consoles worldwide performance. Over 5.3 million PS4 systems have been sold through around the world as of February 8th, ahead of its release this Saturday in Sonys home territory of Japan. The last sales figures released by Microsoft indicated that 3.9 million Xbox One consoles had been sold to retail channels worldwide as of January 23rd. Sony managed to sell nearly double the number of systems last month in the US, Microsofts traditional stronghold.
