Sony has announced a more powerful version of its PlayStation 4 console at an event in New York. The PS4 Pro will be able to render more detail in games when connected to an ultra-high definition 4K television. A cosmetically redesigned, slimmer PlayStation 4 was also announced and will be sold at a cheaper price. One analyst said releasing an upgraded console so soon after the PS4's debut in 2013 took the company into "uncharted territory". Sony is currently thought to be leading the console race, after announcing in May that it had sold 40 million PS4s. Microsoft said it had sold 10 million Xbox One devices in 2014, but has since stopped reporting its sales figure.
