This is an excellent post and it perfectly describes the problems with Nintendo rushing to release the NX.  

On the Gamecube, Metroid Prime I and II, Star Wars Rogue Squadron II and III, Resident Evil all pushed the GCN well past what people were expecting graphically.  I think at the end of the Gamecube's life people really felt that the hardware was starting to hold back the games.  Aside from Xenoblade, I can't think of much that's pushing the Wii U graphically (Zelda and Metroid could have gone a long way to help here).  Even more importantly, the gamepad has not been fully utilized and now that we're finally seeing games like Mario Maker and Star Fox that might start to take advantage of the gamepad we're seeing signs that Nintendo is already done with the Wii U.

Even the Wii saw a lot of maturity with its motion controls.  I really felt tapped out at the end of the Wii's life and that Nintendo did all that it could with that console.  PS3 and X360 had amazing things done with those consoles that really made people excited for what's next.  N64 had an expansion pack to push it's graphics past what it was meant to do.  SNES had a chips placed inside of cartridges to expand the capabilities of the console.  All of these consoles cried out for something new at the end of their lives.  I don't see any of this from the Wii U.  Like you said, I don't think that Nintendo has even figured out how to make HD games in a reasonable timeframe yet much less make a proper open world game.  A newer console is only going to make the development process even harder for them since they haven't even figured it out on 7th gen hardware yet.

Now, Nintendo may have some really interesting ideas for what the NX will be, but I also want to hear why the Wii U was holding back the types of games that Nintendo wanted to make.  At this point, it doesn't look to me like Nintendo is anywhere near pushing the limits of the Wii U.  If the NX is primarily being released for financial reasons then the Wii U is going to be looked at like the Sega Saturn.  Moving Zelda to the NX in any way will only make it look more like Nintendo is ducking and running from the Wii U.  Yes some fans will come back, but when you take people's trust for granted you can find yourself out of a job pretty quick.

I hope that Nintendo does the right thing and continues to support the Wii U by announcing some high quality 1st party titles that we do not yet know about.

Handheld... console!

OT: You want it on the NX? Screw that. Imagine the possibilities if they made it for the following console!

I wouldn't want it to... :/

Which is why I highlighted the fusion (both console and handheld) concept as an exception

I would prefer it on NX as a launch title.

The Wii U is selling bad and Nintendo can't keep releasing high budget games for it: Software has a hard time recouping dev costs already, how are they supposed to make money with a high budget, open world Zelda game that only sells 1-2m units on the on-life-support Wii U in late 2016? I'm sure Nintendo wants you guys to have your Wii U Zelda game but they can't continue to burn money on the console. The Wii U is a failed concept with an expensive controller their first party developers are still struggling to integrate into their games 3 years after the release of the console. They need to move on and release a new console.

So you think a good alternative would be to release it as a NX launch title? How many people are questioning getting the NX at launch? They need to please their fans this gen before moving on. If they have any common sense they would realize selling a million or two more won't be worth alienating their diehard fanbase. 

i think it's going to be a Twilight Princess situation as a cross-gen release. i wouldn't be surprised if that's why they delayed it.

Honestly, I have bought every Nintendo home console until now but if they don't do a Zelda for the WiiU I will never buy a Nintendo console again.

Zelda is probably the main reason why I bought the WII U. 

if you are not sure about nintendo, you don't have to write them off completely, just play the wait and see approach.

It's completely worth "alienating" their "diehard" fanbase. People whined and complained about the Wii because they were "alienating" their "diehard" fanbase. People got mad when Zelda was delayed because they thought they deserved a new Zelda game. Then the Wii came out and broke records, ran out of stock, and went on to sell over 100 million consoles and make Nintendo billions.
