By March 2015, combined PlayStation 4 and Xbox One sales will reach 30 million units, according to Ubisoft CEO Yves Guillemot. He gave the figure today during a post-earnings financial call.
Right now, the combined install base of the PS4 and Xbox One is somewhere around 10 million units. Sony has sold 7 million PS4s, while Microsoft officially sold 3 million Xbox Ones by the end of 2013. Microsoft has not shared a new worldwide sales figure for the platform so far in 2014, but the system sold 115,000 units in April in the US alone, so the number is actually north of 3 million.
