I don't think it will, if lower price, Slim and Pro and the likes of MGS and Uncharted and Final Fantasy didn't help it beat 2015 by a significant margin, there's no secret sauce waiting in 2017 that will drive a similar increase.
It seems that my insistence that a 20 million selling calendar year for the PS4 will be quite difficult to achieve after all, and I still hold to it not beating the PS1 in lifetime sales.
I think the PS4 will be either more or less flat, or even slightly down yoy in 2017, from where I'm sitting, I can't see any major reasons to think it will grow. Besides; the yoy increase for 2016 is easily well within the margin of error, meaning that it can possibly even be down yoy.
Edit; wow, my year end hardware predictions were pretty good for 2016!
