Higher resolution for video games is not a new concept. That has been done several times before.

The first quote you provided says neither Wii U or 3DS which is the same thing Iwata said. A new way to play games (a brand new concept) obviously refers to control input while "pure replacement" doesn't divert from what Iwata said before either. Kimishima is merely repeating what Iwata said. The words are slightly different because the translation isn't an official one from Nintendo.

The second quote means that the Wii brandname will be dropped. Nintendo systems have had various names, so a new Nintendo system having a different name and succeeding an old system isn't anything new either. Considering how the Wii U sold, it's no surprise that Nintendo would drop the Wii brand.

As for my sources, the already provided quotes do the job already. Your interpretation of the quotes is flawed, that's all. You are on a sales website, you know how terrible the Wii U is selling, so why would you expect that NX won't succeed the Wii U? Why would Nintendo spend additional resources on Wii U games when the system is as good as dead? NX was always going to succeed both the Wii U and 3DS since Nintendo had already talked about combining their R&D departments for home consoles and handhelds, because the technological differences weren't as pronounced as they were before, so keeping home consoles and handhelds as separate entities wouldn't make sense anymore. The benefits would also apply to game development, hence why NX was not to replace 3DS or Wii U, but rather 3DS and Wii U.

Nintendo had to find a way to support both a home console and a handheld with first party games on a more consistent basis, and when you know that, you can make the next logical step and rule out that Nintendo will support 3DS, Wii U and NX all side by side. When NX launches, the end of 3DS and Wii U will be near. Nintendo won't support three separate platforms, but only one that consists of a home console device and a handheld device. That platform is NX.

You can read up on Nintendo's Q&A sessions with investors on this website. Scroll through the newsfeed and look for "Q&A" to access the various sessions. The earliest hints at NX date back to early 2014, so a good year before it was announced. Early hints include the mention of combining R&D departments for home console and handheld, measures to improve the quantity of first party software output and the intention to redefine what a video game platform is in a good two years (that would be 2016, but alas, eventually NX got delayed). It may seem lazy that I don't point you directly to all NX-related information, but there have been a lot of Q&As over the years. Check it out if you are interested.

Insider reports, but it can be ascertained from public and semi-public information and simple conjecture. But like RolStoppable said, it's meaningless when specifically production has ended...the fact is Wii U will be no more by 2017.

Oh thanks for clarifying it... So they have these 700k units ( if they're truly so many ) in factory ready to be shipped through the fiscal year, eh?

So in the end the system is going to sell about 14mil total. Wow...wow

I don't know...it was a off-hand comment made in passing. I'm not a Nintendo employee...we hear a lot of chatter and get a lot of reports that never get made public, but I don't have specifics about Nintendo's logistics and supply chain.

The Wii U is so completely irrelevant that nobody cares about it anymore internally. Everyone's laser focused on NX.

But applying my knowledge as an accountant one would assume that 700K means the monetary aggregate of finished + WIP + Raw Materials - DM in the Inventory B/S line item, so only 100K extra procured for further production.

Wii U production is being repurposed for NX production so it makes sense that Nintendo is manufacturing so few units. There's no point in wasting machinery on a failed console...the opportunity cost is just too high.

                                They have to make money till the March 2017, though! Anyway!

What about Japan? They had unexpectedly ( for them ) very big holidays there thanks to splatoon and to a lesser extent to super mario maker,  probably they ran out of wii u Japanese inventory, since it faced shortages soon after, that Nintendo hasn't fix as of now...

Imagine, sales and shipment comparison in March,  showed that there was almost no wii u stock in Japan...!

Since then, wii u selss 4k every week, they obviously constrain the supply  ( I have inferred that Nintendo ships 4k wii u every week in Japan and they sell that out !) This happens because the remaining  inventory is tiny or inventory depleted and they had to manufacture wii u but because of NX they can't produce  a sufficient amount/production pace being extremely slow?

Yeah! Falling from the 3.2m shipments to  only 800k in the current fiscal year, because NX anticipation/wii u premature abandoning!

The 14m isn't representantive for the wii u, it had still some potential, sales could  be more, ( perhaps 16-18m) , if Nintendo wanted to keep it  and try a bit more, but  they  wanted to get rid of the it  as soon as possible, all of their moves manifested that...

The hell, they had extremely well holidays last year in Japan thanks to splatoon ( mainly ) and super mario maker! They didn't attempt at  all  to retain that momentum or fix the shortages that the unexpected huge sales for Nintendo, had caused...
