XB1 is probably ~35m now.... so if it does 5m next year, it ll be at 40m.
PS4 is most likely like ~75m now after holidays. So if it does 10m next year, it ll be at 85m.
So your actually predicting:
hmmmm.... That seems like a really pessmistic prediction for PS4 & XB1.
I think PS4 does like 18-19m next year... and ends up around 93-94m.
Oh, I based my predictions on the nummbers that are shown in the homepage Xp
But I think the Xbox One will stall this 2018, since theres nothing much coming to it, that is not going to PS4/PC/NS too...
But yeah, I have seen the future and is not that bright for Xbone and PS4 =p
