Speculation of a system that is supposedly still in development.

No different than the 2015 lineup.

Based on what though? You have nothing to base this on, at least the other side has several quotes, news reports of dev kits in the wild, time line comments from Nintendo's president, hardware deals Nintendo signed which go into production this year, etc. etc. I mean it even has games announced for it, lol. How many PS4 games were announced 2 1/2 years ahead of launch? 

There's nothing substantial on the "it won't launch this year" side other than people who desperately think "5 years of support" makes a system 10x better or something (basically a gaming old wives tale as plenty of people to this day talk of their GBA, XBox, Dreamcast, etc. very fondly). 

I don't think the mention and or ommission of certain platforms are strong enough indicators as to when a product will be launched / retired. Equally, you could read between the same lines and take the quote "we are creating a new membership service called “My Nintendo” and a new account system, which should work as a bridge between our dedicated video game platforms and other devices" - the plural is emboldened here - as this refers directly to the 3DS and Wii U.

In fact, even that famous graphic about the membership service - with the computer, tablet and phone on one side, and the 3DS, Wii U and NX on the other could be interpreted the same way.

Dates have been deliberately avoided here, because, true to their word, they intend not to reveal any details about the NX until some time this year.

And none of those quotes, ect place the actual console at releasing this year.

Damn. And here I was looking forward to a unified platform this year.

Still, those are concrete examples. 

There's no quote or no indication from Nintendo whatsoever that the system won't launch in 2016 at all. Zero. Zip. Nada. None. 

Until I see all these magical new Wii U software announcements that are going to make the system viable for another 2 years, my personal feeling is there's far more evidence pointing to a 2016 launch than not. 

I mean why even let this question linger if the system is not coming out in 2016, just say so. Why have it hang over the Wii U and 3DS like this? What good does it do for the Wii U/3DS? Just say it's for 2017 then or later. They never announced a NX release date or any details so no one can say they delayed it. Why keep it an open question? 

Only concrete evidence that it exists, and yes I think we all agree that it exists, and that it is close to announcing it. Hell, a few months to a year is all that seperates our views.

Even in this logic, if it "exists" that means games have to already be in development for it. 

Which system do you think is going to get the next Animal Crossing? The next Splatoon? The next 3D Mario? 

It ain't going to be the Wii U, even in that case, the Wii U is just going to get the crap side of support because Nintendo has to launch strong with the NX or they are finished as a hardware maker for good. 

So all priority internally has to be for the NX, people forget it may as well be 2017 for Nintendo's designers, where we are as the "consumer" is basically always 2 years behind where these companies actually are because games don't make themselves overnight. 

The NX will largely be a success of failure based on decisions and effort Nintendo is making right now, today, and even from last year. The PS4/XBox One are basically a master class in that concept. 

True, but then again having the LoZ team free to start work on its own ground up NX title for a year would mean one less year we would supposedly have to wait. That could turn tides as well.
