Um... they have abandoned ship one time before, about 20 years ago.

When Nintendo's consoles struggle, their response is to throw MORE support behind it, not abandon it completely.

Sorry bout that I can't read sometimes.

I personally believe that the Wii U will go to 2019 if planned right. Plan is that they move at least 7 mil a year, release great games and release a Military FPS with a good campaign and CoD like multiplayer wit BF4 environment and Halo vehicles and weapons damnit!!! This will cause an internet explosion.

A new console from Nintendo in 2016 would make things really interesting.

They're not going to say" We aren't going to produce the Wii U anymore because it don't sell"In fact they will never admit it. They would prefeer to act as Luigi scared and confused running from one side to the other as an idiot in the haunted mansion that say: OK we really screwed this time!Sorry!

The Wii sold over 100 million consoles and was their best selling home console and it lasted 6 years but the final year was not supported much, so their best system by far was supported 5 years. The last real support the Wii had from Nintendo was LOZ SS in 2011 a full year before the Wii U launched. It was pretty much abandonded in spite of having the largest user base since PS2.

Not sure how anyone can believe that we will see 3 more years of support on a console with so little demand. We can expect a Legend of Zelda game, Fire Emblem crossover, Yarn Yoshi, and maybe another Mario title/sport spinoff (there have been 2 and a DLC retail release already in the first year). Pikmin, Wario and DK are done this gen for Wii U, Kirby, Star Fox, and F Zero are unlikely on Wii U, Wii series is probably done, and a Metroid is probably not going to give the Wii U a boost, maybe a 3DS title. What's left? Maybe a new IP or 2 a year or more from now?

At this point, anything left for the Wii U will be announced this E3. We know third party games are few and far between and any that they do get will be on other consoles as well. I can see next year being the last year of support by Nintendo with a successor releasing by fall 2016 latest without a doubt, with major support running out by holiday 2015, and anything still be worked on hitting in early 2016. 2012-2016 seems to be long enough to save face and early enough to keep investors from jumping.

So far all year we only had Lego Movie and DKC. For the year, so far we can expect.

Mario Kart 8
Smash Bros.( which is also on the 3DS, so anyone who really wants just that and has a 3DS will just get that version) Bayonetta 2
Amazing Spider-Man 2 (multi console)
Sonic Boom
Transformers (multi console)
Watchdogs (multi console, delayed on wii u, might be cancelled)
X
Hyrule Warriors
Project Cars (multi console)
And a handful of downloadable titles that don't scream buy a Wii U

LOZ and Yarn Yoshi have no solid release date and could easily be delayed until next year. It seems like Nintendo is already slowing support if you can count. We might see a few more third party titles release this year but it's doubtful that any new announced games from Nintendo will release this year. We could literally see 15-20 retail games release for a whole year for Wii U. I may be missing a few titles, but there are whole months this first half a year with literally 1-3 retail games total for the Wii U, do people really think there are so many games in development that we don't know about and will suddenly explode onto it?

Edit:  And looking at the NA releast years of Nintendo consoles, we had...

NES 1985-----SNES 1991-----N64  1996------Gamecube 2001------Wii 2006-------Wii U 2012   you almost see a pattern here where the years end in a 1 or 6, on average Nintendo only supports their consoles about 5 years almost consistantly, but with the poor state of the Wii U, I think they will end this a little sooner.

Nintendo has 5000 internal employees and 2000 external. EA and Ubisoft have 9000 each. Konami has 5000.
Nintendo support both hardware and software on two plattforms with less people than EA that only has to make small changes every year to their annual series.
Almost every game that comes out of Nintendo are getting high scores on metacritic.
Sure they could work smarter and give us HD versions of Gamecube and Wii games, they could work smarter and buy studios, they could work smarter and look around the world for forgotten PC-game gems to be converted to WiiU.
But it is hard to tell them what to do, they have been in the ups and downs of the industry and have some knowledge of what the consumers really do as opposed to what they say they will do.

Ungghhh, more negative stuff...

The the OP, I believe they will support the Wii U for their usual cycle of 5 years at the minimum. They have only jumped ship on a system once ever before, there's not a proven history of this occurring.

I'm getting the games I want which includes Zelda WiiU, MK8, X, Yarn Yoshi and who knows what more

so I won't be a nagy bitch and ignore all the games that are out and are coming because I think they will drop support like they did with Wii as it gave me hundreds of fun hours and so will the WiiU
