More than 9.7 million Sony PlayStation 4 video games sold

There were more than 9.7 million Sony PlayStation 4 video games sold to support the impressive 4.2 million consoles sold before the end of December 2013. Sony officials "couldn't be more thrilled" with the early success of the PS4, and it will be a great battle to see the PS4 compete with Microsoft's Xbox One game console.

The global demand for the PS4 is outpacing the Xbox 360, as Microsoft finds success in the U.S. market, while overseas shoppers tend to jump onboard with Sony. Both Microsoft and Sony will battle to control the next-generation gaming market, though it looks like Sony has the initial international upper hand.

Video games were on full display during the 2014 Consumer Electronics Show (CES), where Sony, Microsoft, and Nintendo showed off their latest product innovations. Sony's PlayStation Now streaming game service, which is scheduled for launch this summer, will be a cloud-based game streaming service for PS4 gamers.
