3. Enhanced communication
Online gaming is a great way to keep up with friends without having to ever leave the comfort of your own sofa, Kinect Video is an interesting feature, and the integration of social media platforms on consoles is nothing new, but next gen consoles should make great advances in the communications space.
Earlier this month a Microsoft job ad revealed that the "next gen Xbox" will support Skype. The potential to make or receive free phone calls on your console is an appealing one, particularly if it means you can simultaneously play games, eradicating the need to juggle your mobile phone or telephone receiver with your controller.
The Wii U will also go in this direction, allowing customers to make video conference calls with their devices.
