The battle between the Xbox One and PS4 keeps raging, and it looks like Sony's got the upper hand. Microsoft had announced sales of 3 million Xbox One units for 2013 earlier this year, but that considerable figure has now been overshadowed. At the Consumer Electronics Show, Sony CEO Andrew House announced that the company had managed to sell over 4.2 PS4s in 2013.
In addition to this renewed assault on Microsoft's efforts, Sony also revealed details of the new PlayStation Now streaming and cloud TV services. Beta-testing of the services will begin in the US by the end of the month, which will see features like instant access to PS2 and PS3 games being rolled out.
