2015 is the peak yr for Wii U, so with a mostly slow 2016 I think Nintendo will launch NX hh in Q4 '16 (5.5 yrs after 3DS), with NX home shortly after its E3 '17 focus, or Q2/3. I don't think Nintendo will treat their next home con. as its "own" console where it gets a traditional holiday launch, just a new member to the NX line of products.
