WiiU's are sold every day. People do not only buy consoles for one game. I did not buy my PS4 only because of Street Fighter V. I also bought it because of what I know is coming out, and because of what I expect will come out that hasn't already been announced.
There are people who expect that WiiU will get more quality games over the course of 2017, and even 2018. And there's absolutely no reason for Nintendo to have more people who will skip out on buying a WiiU for even a single day, if they can easily avoid it.

No, the reality is that they wouldn't have responded to these reports constantly if they thought they had "like 0" to gain from it.

They have everything to gain from denying these reports, and would only stand to lose sales if they didn't. People are hired specifically to prevent this kind of thing, and so they do their job.
You think these companies purposly flush money down the toilet when all they need to do is type up a sentence and press "Send" to mitigate some of the damage. And that it's ok as long as it's not "too much". That's not reality. You also didn't seem to understand why they would want to keep everything regarding a new console under NDA instead of just a few things. As I said then, it's because it's more simple and efficient, and covers all their bases that they may not have foreseen. So you don't seem to understand the importance of structure in a company, as you're also trivializing unnecesary losses that can be easily mitigated with a simple comment.
There's no data to support your claims of how little they stood to lose here. But we do have angry comments from people saying they will no longer buy a WiiU, or never buy another Nintendo product again, after this news broke. For some people, this isn't just a concern about when NX will come out either. Discontinuation casts doubts about continued WiiU support after NX comes out, and one person I talked to was worried that they would shut down the WiiU servers early because of this. Etc.  Even Nintendo can't be certain of how much money they could lose because of this. But they do know it upset people, and that's why their PR team went to work on this. Because it's simple for them to mitigate the damage. While losing sales doing nothing is pointless.

Simply put, they would not have responded to all these Nikkei reports if they didn't consider the information harmful to them in some way.
And if they didn't their PR team wouldn't be doing their job.

Of course you can still make comparisons in order to establish credibility, a pattern, etc.
If Nintendo had never ever lied when they denied these things from Nikkei, I would be extremely inclined to believe Nintendo. But since they've lied on these occasions numerous times before (I don't know how many, but four times is plenty), we can be 100% sure of one thing. Nintendo's word here means nothing and holds no credibility.

On the other hand, Nikkei are a well respected publication, and have a track record of being accurate in their reports.

Hence I'm inclined to believe Nikkei until they give me reason to doubt them, like Nintendo has.
That's the difference between taking these facts into conciderations and just ignoring them.

Have they been developing mobile games for the past two years? Did they release further details in late January 2014? Are the released games mini-games?

Liar.

The user was warned for this post - VXIII.

Actually yes, Nintendo revealed during the smartphone announcement that they had been looking into smartphone development for like a year+ beforehand and "mini-games" is kind of a catch all term for any smartphone game as the games tend to be small, bite-size experiences, which pretty much describes Miitomo to a tee. 

Yes there would be a loss in sales for this announcement.
You have no evidence supporting your claim whatsoever. But I have evidence that supports mine. Just pick and chose among the many comments on the subject.


There are plenty of other comments like this. People are mainly worried about game support in 2017 when they heard this. Some say they'll buy a PS4 instead. And you know why that is bad? Because if they had waited until E3 and seen NX first, they may have been impressed and not have spent money on PS4 instead. There are many more factors to consider that you seem oblivious to.

I've told you time and again. There are reasons for why there's a time and place to make certain announcements.
Nintendo would not have their PR team respond to these reports if they didn't fear negative consequences.
