Doing maths with PS4, I'm starting to believe PS4 will reach 20M sold this year too. PS4 sold around 9M the last 3 months of last year. I expect PS4 selling even more this year, maybe around 10M, according to this site PS4 near 84M at the end of september, so that will put PS4 near 94M total sales lifetime. According to Sony PS4 sold 73'6M by the end of 2017, so that means another 20M selling year for PS4...and everyone is disussing about PS5 being next year.....HA!.
