If we stagger the planned launches to the max:
NX handheld -> Spring 2017
NX home console -> Spring 2018
And at the earliest, based on latest Digitimes news
NX handheld -> Fall 2016
NX home console -> Spring 2017
I think most likely timing is Fall 2016 for NX handheld, then Fall 2017 for home console
I predict NX launches in 2017 - not 2016
