XBOX is loosing to PS4 but still it's not a Loss.. it's just that PS4 is more popular.
I think XBOX will easily hit 60-70 milions while PS4 will hit 100
Being behind doesn't mean = looser. 60-70 mil means being relevant.
XBoxOne will never reach 60-70M according to current trend. PS4 has sold more than twice than One, and continues to outsell the MS console by more than 2:1. PS4 will most probably hit 120M plus by the end of its life cycle, no way it can stop at 100M, considering it might reach 95M plus by the end of this year. You shoud review your calculations....PS5 is not gonna happen before Nov 2020, and PS4 will continue selling after that time, anyway.
That said, I don't consider XBox One a failure, of course, it still is a productive console, and plenty of good games.
