At Gamescom in Germany, Sony has announced that the PlayStation 4 has sold over 10 million units since it launched nine months ago in November 2013. Meanwhile, Microsoft still hasn't released any recent sales figures for the Xbox One, suggesting the console isn't doing all that well. Our estimates put the Xbox One at around 5 million units sold through to customers -- or about half the total sales of the PS4. According to a fateful quote by ex-Xbox chief Don Mattrick, it would appear that the PS4 has won this generation's console war.
