I'm 3/13 so far. Shantae, Pokken, and surprisingly Doom have all come or otherwise on track to arrive.
Since RE4 is probably not far off with the arrival of revalations 1+2, that's probably #4.
Recent rumors in consideration FFXV may be a possibility too!
The Mario x Rabbids collab shows there's a pretty deep relationship b/w Ubisoft and Nintendo now, so several more things ought to be queueing up (Red Steel, possibly AC too)
The only thing I have genuine doubts on is Overwatch as there's no indication Blizzard is willing or capable of taking that on.
Seems like Undertale could end up a PS console exclusive. Whatever.
I predict NX launches in 2017 - not 2016
