Nearly 2:1 in 2015 isn't "close". The only reason you may be fooled to think that is that we're (unfortunately) talking about small numbers all around when compared to healthier markets. (Just as an example, PS4 is #1 home console of Japan in 2015 with almost double the sales of #2, the Wii U, yet in almost 12 months it has sold 400k less than what PS4 sold in the US in November alone).
It'll happen before NX. The gap this year is almost 600k in favor of PS4. There is around 700k left I think? In 2016 the gap will be even bigger.
