even so, wii U is selling better this year than 2014(i didnt expected that), even without games with the importance of mario kart and smash. also, they are working more in previously annouced games and third party developers to keep the library going until the NX arrival. I and lots of wii U owners are ok with splatoon, mario maker, xenoblade, zelda, pokken and some other titles until the end of wii U life.

but i see your point and agree mostly.

But will NX be 9th gen? they are of course diminishing the 3DS and wii U support to focus in NX, but NX can be also 8th gen, so perhaps they are not done with 8th gen.

What are your rules here? If it's about Nintendo games announced in 2015, then with minimum effort I can already think of Twilight Princess HD that you missed.

Constantly worse than 3DS despite being newer and just plain bad in general. I've been saying both systems will be replaced btw, not just one or the other, for the reasons already explained in the OP.

As I said before it would be a terrible decision for Nintendo. They will only sell half of the systems from then because one is literally useless.

No company with some sort of economic sense would do that.

But we already have our big Mario and Legend Of Zelda game announced (and Mario being out for a few years). They could easily announce a new Metroid for Wii U and gain some excitement even if they announce the successor to Wii U. 

I also expect a 30th anniversary LoZ show at E3 that will be around the same as their 25th in 2011 and Skyward Sword E3 (with Wii U reveal). 

*Edit* I also felt it was of note to say that the project rainfall games weren't announced for release until after E3 2011 and reveal of the Wii U.

If they stop supporting 3DS n Wii U (which they will ofc), then it has to be 9th gen since the only option is a third pillar alongside 3DS n WiiU, which would be software suicide.

Yeah, I'd say Ninten is about done with both the 3DS and Wii U at this point. Though Nintendo has pretty much exhausted the 3DS as it has gotten plenty of software from them. Wii U hasn't as much, but considering how they had to manage a console mostly on their own, they have done a pretty good job. The only time I found their quality to be in question was in Ultra Smash. Aside from that, not bad for them.

Also, we're stilling getting some games in 2016, so it's not all bad x )

Seems more like Ninten is just done with 2015.

Like the thread title says, Nintendo developed retail games announced in 2015.

That might not be as bad as you think. Nintendo games always have great attach ratios, so not dividing the userbase by half is a great way to get people to buy more games, because now they are not limited by the choice of one piece of hardware. Imagine, per example, that the WiiU and the 3DS were one single system. We'd have a system that has sold around 60-70m by now. But now look at the software numbers:

-Mario Kart7+ Mario Kart 8

-Smash Bros U + Smash Bros 3DS

-New Super Mario Bros 3DS+WiiU

-Mario Maker in a 60-70m userbase

-Splatoon in a 60-70m userbase

-Pokemon in a 60-70m userbase

-Zelda U in a 60-70m userbase

-Mario Sports something in a 60-70m userbase

-3D Mario in a 60-70m userbase

Just those numbers alone are worth it. If they can save money by just making one version of their games, and save time and resources that can be used in more games, that almost doubles the efficiency of the company. They save money, they can make more games, and they give 3rd parties one bigger userbase to work on.

Yeah, they seem unable to keep up with 2 systems, a third pillar would bury them.
