Oda said, “Sales of PS4 exceeded 53.4 million units worldwide, and the sales total of PS4’s game software reached more than 400 million (401.1 million),” , “2016 was a year when we were able to offer a fruitful product line-up,” PS4 with a slim shape, PS4 Pro with further improved performance, and PSVR .
