Not wrong but...
I won't exclude new Wii U retail releases announcements and/or price drop. And we also don't really know what's the nx schedule release is. February, after the next corporate meeting, could give us a better picture. Maybe.
Well of course I am basing my prediction on what we know.
If wiiu will se a price cut to 99 bucks, a sudden release if many unannounced games,a minecraft nintendo edition retail release with bundle and dqxi at the same time of the 3ds I think it will sell better than 14
I expect every system except PS4 and NX to be down YoY.
NX: Most likely supply constrained.
3DS: less than 2M
PS4: 1.5M-1.7M
WiiU: 650K
Vita: 800K
PS3: 100K
XBO: lol
That is I expect YTD in 2016 to be lower than the record low 2015 without NX.
EDIT:
BTW who expect WiiU to outsell GC in Japan?
GC LTD is about 4M.
If it will die as quick as other nintendo consoles after the announce of the new hw it will not hit the 4 millions mark
