Let's look at Wii U then:

Twilight Princess HD: Outsourced to Tantalus

Starfox Zero: Outsourced to Platinum

Shin Megami Tensai x Fire Emblem: Late localization

Pokken Tournament: Late port

Mario & Sonic at the Rio Olympics: Outsourced to Sega

With the exception of Zelda U, Nintendo has well and truly moved on from Wii U, their major studios are likely all deep into NX development.

A better selection of the games they bring to the system will help. If the audience buys colourful games and RPGs, bring Grow Home and Cild of Light instead of the next AC. Some games will sell no matter what, like the FIFAs, but if one kind of audience has proven profitable on the system, catter to them first before pulling the plug. After Splatoon, I'm sure EA would like to bring Plants VS Zombies to the NX (if they bother to properly support the console this time). Activision will continue with Skylanders because it's successfull on the WiiU (and they could even add some cross compatibility with amiibos). Ubisoft has Rayman, and that sold well on the system, so it would be plausible to bring it to the NX. Companies less focused on family-friendly games might not be supportive at first, but if Xenoblade Chronicles X sells well, it may attract a couple of ports from Bethesda or T2.

But I'm sure the support Nintendo really wants, from beginning to end, are the eastern publishers. Those companies supported and kept the Vita alive in Japan (and basically everywhere else), so they are crucial to fuel at least the NX handheld. With the Vita not getting a successor, it looks like the NX will have to compete only against the mobile market, and that may change if the mobile strategy Nintendo is following gets integrated on their hardware. Imagine all the games the NX could suddenly get if those companies port their Vita games to the NX, decent 3rd party support for a couple of years.

Well Nintendo could actually develop other titles that appeal to the same market that Ubisoft and other 3rd party publishers target.

You only have to look at the kind of games Nintendo releases, then look at the kinds of games they don't to see that there's quite a large range of stuff that Nintendo could try their hands at making to gain more attention from the market as a whole.

Hell indie studios are showing that you don't need huge AAA budgets to make awesome games, you just need flexible tools, ideas and a bit of time to work your ideas into something tangible. When studios like Hello Games can make galaxy sized games, with mountains of gameplay potential or a studio like Media Molecule can make a digital creation platform, with unlimited creative potential like Dreams with fewer than 60 people well Nintendo shouldn't have any issues churning out a bunch of awesome games that appeal to more than just the faithful core Nintendo audience.

If Nintendo had reacted fast enough they could have kept 3rd party coming to them with something. Wii U is still capable of running a lot of the 3rd party games we've seen, just not at the resolutions or with all of the visual features that PS4 and XB1 are capable of pushing.

It's Ubisoft so I won't bite, but I voted yes for the lulz!

Yep they've stated lot's of things, some of which were lies or never came to pass. That's why actions speak louder than words, and why their 2015 game announcements have painted a clear picture for 3DS and Wii U's future. And yes it is a fact that Nintendo's announced in 2015 games are either low budget or not even made by them. I mean do you honestly believe Amiibo Festival took serious effort? Almost all of them reused assets and engines from other games, that's obvious just by looking at them.

SMTxFE and Starfox are not made by Nintendo but by Atlus and Plantinum respectively, but regardless most of those games you mentioned aren't as telling since they started being planned or worked on before the Wii U was proven to be beyond saving. Hell the only 2016 Wii U game that we didn't already know about years ago is TPHD, a slighty better than a port that's also not even made by Nintendo. So yeah, I think all this outweighs that statement you didn't even provide a source or context for, the latter of which being important because yeah, technically they are still supporting the Wii U, just not nearly as much as normal, and not for much longer. Also are you implying Pikmin 4 is for Wii U cause the fact that they didn't reveal it in the november direct despite it being near completion says otherwise.

EDIT: Ignore this and respond to Hiku already.

Interesting ideas for expanding the audience, but they are only small things that will help. Family focused games arent too bad (Nintendo is basically gauranteed just dance, skylanders, and rayman), EA is the only issue with FIFA and P vs Z support.

But in order for the mature third party to comeback, 1 or 2 good games aren't enough (otherwise bayonetta 2 would have made third party games comeback).

Nintendo needs 3 things:

1) Crazy easy development tools - it has to be easy and cost effective to port for the NX. Publishers have to think "We may as well port to NX since its cheap and easy money" instead of "make the ps4 version THE place to play"

2) Better communication with third parties - no. 1 reason why bethesda never gave the wii u a chance, big reason why publishers liked working with the ps4.

3) Third party exclusives - games to associate Nintendo with to expand their audience. When people say bayonetta, they now think of Nintendo. This needs to be the case with more highly rated mature IP (xenoblade is also good).

Lots has changed in the past few years and I think NX will have to reflect that ...

- The home console business .... Nintendo's is largely irrelevant in the market. And the home console is largely dead in Japan.

- With increasing technology, Nintendo can no long support a seperate handheld and home console (neither can Sony or MS). This isn't the Game Boy era where you could half-ass a couple of Donkey Kong Country ports and 2-3 other projects made by a team of 10 people and that was good enough for your yearly line up. Nintendo fans that think can just keep making consoles and handhelds the same way forever are naive. Today the 3DS requires a ton of resources and requires its own mainline Mario, Smash, Mario Kart, Zelda, Animal Crossing, etc. games, in fact it's arguably now the lead platform for some of these IP.

- The impact of mobile on Nintendo's handheld business has been devastating.

I think that the NX will be a handheld and a home console.  I hope that it can play 3D like the 3DS, which I think is the next level of gaming and movies.  All I know it's that I trust Nintendo.  They are bold and brave and they have a goal to give the gamer a good experience that they can be wowed by.  They do what they think is fun and right - for example - releasing a purple Nintendo GameCube!  That probably wasn't he best idea but I love that they did it.  Nintendo has always been ahead of the game when it comes to gaming ideas even if the graphics haven't been as powerful as their rivals.  Their games are hard - Mario Galaxy, Zelda: Skyward Sword and even Donkey Kong Country 5 - hose are examples of hard games.  They will make NX greater than any system before it.  

It's as legit as Donald Trump's political career!

(Ahem, that isn't a good thing)

My bads, I seem to have givin him a scapegoat. I'll just let you deal with him then!
