It should be noted though at least in Japan, 3DS sales got a boost for about a month and are now down to where they were before Pokemon Go launched.
So while the bump is decent and notable, it's not as if suddenly 3DS is selling massive amount of qualities and things like a YoY bump are easy to have occur because its sales last year weren't great, so you're starting from a low basis.
Of course there will be some spill over, I'm just not convinced right now that it's massive. If 3DS tops Nintendo sales forecasts this year by a large margin, buoyed by Super Mario Run and Pokemon Go, then I would say an effect is happening, but a 1-2 month blip and then a gradual settling down is better than nothing but it's not the be all, end all either.
What I think NX will do is as a platform it will bridge the gap between mobile and Nintendo portable, by allowing the play of smartphone apps directly on the device. So if the mountain won't come to Nintendo, Nintendo will go to the mountain and set up shop at least.
