I'm 99% sure it will be released for the NX launch, or at the same time as the release of the WiiU version.

I think they will push back the release of the WiiU version just to match it with the NX

Nintendo has never ported older games to a new console; TP being the only exception. So I don't really understand the argument that most late Wii U titles are going to get an NX port (assuming the NX is a home console).

We know it's coming to the Wii U, that's for sure. The NX? I don't know. Only if the NX is a home console and releases this year. Then there's a chance, but until that is still unknown, I don't even know why this is up for debate. If you're skipping the Wii U and are hoping the NX will be a dream machine that will have Zelda U as a launch title, prepare to be disappointed.

wow at least somebody who is able to think logically, thank you ;)
People are acting like the game is official confirmed for NX. Its like saying: The last of us 2 remasterd will be on ps5.

Biggest project ever and very hyped game that is coming at end of life of worst selling Nintendo console ever and that is delayed for whole year same like TP!? Definitely is similar to TP situation.

Nintendo intended to release Zelda U in 2015, they said that in December 2014, but they decide to delayed it in March of 2015. I think game is basically finineshed and now they just polished it and further improving it, while in same time they porting it to NX. Whole year is more than enough to port a game, they can done that for 6 months. Zelda team doesn't need to port game because that is all technical staff, another Nintendo team could port game to NX, they basically could start working on NX port right before they delayed game.

You saying TP was port to Wii to show posibilites of Wii Remote, but they already had much stronger title for something like that, Wii Sports. They ported beacuse its very strong launch title and beacuse it they will have much better sales on two platforms and not just on one, (at end TP become best selling game ever) not beacuse Wii Remote. When they decided to ported they logicly included Wii controlls and little improved game over GC version, for instance 16:9 support.

I also dont think Zelda U on NX will have better resolustion or frame rate, but definatly will have some sort of improvment, maybe difrent control sheme, or maybe same content that Wii U version want have...expariancies will probably be indentical, but you missing point, they will not port Zelda U to NX and make it launch title becuse improvments or difrent expariance, they doing that because it would be a killer app on brand new platform (and after fail with Wii U they need very strong launch titles, especially when they will release console in middle of PS4/X1 life) and because game itself will have much higher sales than on Wii U only.

Porting game is not expensive at all, we are talking about few millions, but if they sell just 1m with price of $60 you can easily calculate how many money will NIntendo earn on Zelda U port but I really can't see that Zelda U sell less than 3m in worst case on NX if its a launch title.

I honestly would be ok for it being on both like Twilight Princess was I had no issues with that back then don't see why I would have an issue now.

Guess what, that only exception is also Zelda that was in similar situation like Zelda U is, huge game coming at end of life of worst selling nintendo console till date.

2016. launch for NX doesnt mean it will be rushed launch, you forgeting we didnt had one single Wii U annucment for year and a half (from E3 2014) that isnt small project, port or spinoff. That means Nintendo is working on NX games from 2014 and you can bet that some unannounced Wii U project were moved to NX. Saying that, they can easily have new 3D Mario (Mario 3D World is finished in 2013, around 3 years of development for 3D Mario is more than enuf), Pikmin 4 (we already know that is almost finished) and Zelda U port prepared for this years launch, and thats are very strong launch titles.

In Nintendo eyes, Zelda U is our biggest project ever and there is no sense to leave it exclusive to Wii U, so we are porting Zelda U for NX, we will have killer app for launch of totally new platform and we will sell millions of copies of that games. Its win-win situation with basically no negative sides.

Windwaker HD was ported in 6 month, but from Gamecube to Wii U (both PowerPC). Again, i doubt NX will use PowerPC. 1 Year would be quick. Tantalus is porting twilight Princess from Gamecube/Wii to Wii U and they need 1,5 year (start late 2014, release march 2016). And Twilight Princess was even developed on similar architecture.

The delay is nothing new. Skyward Sword was shortly for release also delayed 1 full year.

But lets just chill and wait. You will see it soon enough ;) Dont be dissapointed if Zelda Wii U wont be on NX, just an advice.

Or:

Nx will fail horrible because their biggest game is just a port from their old system. Zelda fans already got a wii u and will play the game on wii u. NX fails horrible. Instead of wasting development time into porting Zelda Wii U to NX they should better bring own and unique games.

If it really will happen like you said: 1 big 3d Mario, Pikmen 4 and Zelda Wii U port as big games for launch lineup, im sure NX will fail. It will sell even worse then wiiu. Really, really bad strategy.

You're wrong there, Mario all stars for a start, then the were a Zelda collection on GC, Animal Crossing on GC is also an enhanced port of the N64 game that never made it to the west, we also have the Metroid Prime Trilogy.

TP was a multiplatform release and the notion of the next game following suit is not farfetched
