Just off the top of my head ...

Super Mario Galaxy 3 - The main EAD Tokyo wrapped on Mario 3D World in fall 2013, given that it takes them on average about 2 years to deliver a new 3D Mario, summer/fall 2016 should be more than overdue for a new 3D Mario, that will coming up on three years with just Captain Toad which was done by EAD Tokyo's smaller B team. 

Animal Crossing Next - IMO this skips the Wii U. Nintendo themselves admits the series works better on handheld and it sells much better on handheld. Could be a no brainer launch title for the NX fusion concept.

Luigi's Mansion 3 - Next Level wrapped LM2 in March 2013 ... they haven't delivered Nintendo a game in quite some time (that's almost 2 years ago now). Whenever Nintendo sells 3+ million of any game, a sequel is almost always immediately greenlit ... remember when people though Nintendo would let the DKC series rest for Metroid Prime 4? Nope, Retro was put right back on another DKC, which is pretty much Nintendo's standard operating procedure.

Mario Kart 9 - Might be more of a reach for 2016 ... but not impossible. Nov/Dec 2016 launch would give them 2 1/2 years of development time, which is about the same gap of time between MK7 and MK8.  

Ignoring the elephant in the room which might also be the next Zelda launching for both NX and Wii U, like Twilight Princess did. I'm starting to suspect SMT x Fire Emblem might be going that route too. 

If anything a good chunk of Nintendo's dev teams have been oddly ... quiet or MIA for a while. 

That isn't enough to entice gamers to go out and buy the console in a mad rush. This will only get the core buying it.

They need a FPS, a racing sim, sports games. RPG, and so on ontop of that list to give enough variety to entice people.

If your list is the launch window then the system is doomed from day one.

lol

Is just your wishes, not reality

So its his opinion that Nintendo isnt doing well?

The great irony in it all is that Japan was the one region where the most people were sure the Wii U had a chance at winning. I even recall someone saying that "Japan is the gaming capital of the world and is showing us what is to come in the rest of the world; keep your eye on Japan."

At first the mobile deal made me think Nintendo is no longer compelled to rush out new HW. However, pushing Zelda back after that, also tells me Ninty does not want to "waste" SW on a single, esp. low install based platform. I get the impression Ninty wants to aim for a rich library that allows fans to choose the way they play. Nintendo wants the consumer to feel their HW is a "must have", & dividing platforms works against this. They need NX getting off to a good start.

q4 2016 is the ripe time for new Ninty HH.

In Japan, which this thread is about? Yes.

3DS+Wii U are down about 15% YoY, which isn't out of the norm considering 3DS is in its 5th year and Wii U in its 3rd, they are both at a point when sales are expected to be declining and following natural sales curves.

A 3DS successor in 2016 is kinda a given, not because Nintendo isn't doing well but because that's just when a successor was naturally expected to release (5.5 years after launch).

No, Nintendo just needs more games. DS sold very well because there was a steady stream of games always coming out. I'm sure we'll see some more 3DS system sellers this E3 or even on today's direct.

to be fair home consoles arent doing gangbusters in Japan at all

Really? Ur going to use JohnLucas to generalize an entire group?
