If Nintendo had shown us on E3 this:

Zelda Wii U

Minecraft Wii U

Twilight Princess HD

Pokken Tournament

Fast Racing Neo

+ Star Fox + Mario Maker +Other minor stuff

It would be a pretty decent e3.

So wrong. In Wii U case marketing and name are single biggest reasons why Wii U failed. 100m people owned Wii, but all those people in meantime migrated to other platforms and didnt play Wii any more, basically they move away from Wii, and than Nintendo comes with terrible marketing and again Wii name making misunderstood and confusion on market where all those casual thinks that Wii U is actually some kind of addon (tablet controller for Wii), and not new console. Not just that consumers were confused it was same for shops and retailers, it was mess. That misunderstood and confusion last almost whole year, when Nintendo finally had better marketing (around holiday season 2013.) it was already too late. Personally I resseling Wii U games, and believe me there people that still dont know that Wii U exist and that trying to buy Wii U game for their Wii. So only with better and normal marketing that didn't make misunderstood and confusion and different name, Wii U sales would be definitely noticeable better.

Add to terrible marketing and bad name all mistakes Nintendo made with Wii U (that I mentione with) and you have worst selling Nintendo console.

so why failed the gamecube? Because of mini disc format ? :D

Why failed the N64? Because of Card Ridges?

There were also people who bought ps3 games for ps2. Or even xbox one games for xbox 360.. Its more on the wii bcause the wii was a big casual only machine (the only reason the system had success at all) and casuals didnt got it.

I didnt was much into gaming in 2011/2012 but it was very hard to dont see the news a new nintendo console is coming. It was everywhere in the media.

The only reason the wii was a success is because of the big casual market who wanted to play wii sports with their kids or whatever. You just backed this up with your last reply by saying those people didnt understand the wii u was a new system.

The nintendos only chances to get success it to aim at the casual market. And they DONT need zelda for that. They need something like wii sports, candy crush, whatever.

The Wii U´s userbase is probl divided into 50% Nintendo fans and 50% casuals/kids who want to play mario/their parents want them to play mario/mario kart and co).

With 12-13 mio sold consoles, this means that are at best at the moment 7mio people that are really hardcore interested in nintendo games. If nintendo want success, they need to get around 80% of their userbase from the casual market.Like I said before, Zelda wont help.

With NX btw they are already doing bigger mistakes then with wii u. Release mitcycle (where people didnt migrated to ps3/xbox 360, but to ps4 and this system will also be around for a while). IF its nots a casual machine, it will fail. If its a hardcore gamer machine (zelda would make sense) if will fail.

Yes one of reasons why GC failed is Mini Disk, but most important was huge popularity of best selling console ever. I dont think N64 failed, but reason why didn't had much better sales is cartridge format, because capacity was to limited for 3D games, so all 3rd party skipped N64, for instance only reason why Final Fantasy 7 wasn't on N64 was cartridge format.

When you have product more than 3 years on market and still not consumer are aware of it, you have problem, and that problem was directly associated with marketing and later popularity of console.

You are a gamer, you following gaming news and you are informed, but other groups of potential customers (espacily casuals) that largle owned Wii they didn't followed every news or detail about Wii U, and with terrible marketing and name they thought Wii U is addon for Wii, and casuals that has Wii already moved from Wii to different platforms, they didnt want nothing for their Wii they dont use.

You are in denial if you really think that terrible marketing and bad name didn't had any impact on Wii U sales.

Zelda U need if they want to attract core gamers, no one gamer or Nintendo fan will buy console to play Wii Sports or Candy Crash. They need different types of game to attract different types of buyers, you forgetting Wii  had Wii Sports and Zelda like launch titles, perefect combination. On NX new 3D Mario and Zelda U will also be very strong combination, 3D Mario will attract casuals and kids and familys, while Zelda will attract core gamers.

Yes, but point is that Wii U isn't appealing product because Nintendo made so many mistakes, so console was not desirable product to any potential buyers, that's why Wii U have so terrible sales. If Nintendo didn't make just some of those mistakes, Wii U would be more desirable  product and sales would be better. And like I wrote, weak launch titles are one of mistakes made with Wii U, so Zelda on NX will definitely help.

Like I wrote, biggest single mistake for Wii U was terrible marketing and bad name, not release time, but that definitely was one of problems. But Nintendo is in very bad position, beacuse they can't wait around 2019. with Wii U to Sony/MS realase they their next consoles, best thing they in this situation is to release appealing product in mid generation.

Bottom of line you are in denial if you really think that terrible marketing and bad name didn't had any impact on Wii U sales, or if you think that Zelda U like launch title will not help NX at all and that game will not have much better sales.

90% of games at the time could fit on the GC mini-discs so I wouldn't even class this as a reason tbh as even GTA3 could fit on them, people often try to cite them as a reason when they're not really that much of a problem.

GC Mini Discs has 1.5GB while PS2 has 4.7GB, so definitely some games couldnt fit on GC discs, but like I wrote, biggest reason why GC failed is PS2, it was so popular, it was so popular that became best selling console ever.

The Gamepad of the Nintendo Wii U is the most comfortable way to play for gamers like me with big hands. I'm definitely not alone with this opinion. I don't want to miss it.

Most games in the PS2 era didn't even touch 1 GB, the was a link someone posted which detailed the sizes of all the popular games of the era and only a handful wouldn't have fit on a single layer disc and a very few would not have fit at all, the mini-disc excuse is one of the most exaggerated in gaming history as 90% of games would have fit on them with enough space to spare, the average size of a game back then was around 600-700mb. It would have only affected games like FFX that use a tonne of video files.

PS2 era just comes down to Playstation's popularity and the long standing fact that most developers have only ever wanted to develop solely for one platform to reduce work load and costs.

Like I wrote, definitely some games couldn't fit on GC discs, like you wrote FFX is good example of very strong title that couldn't be on GC disc. I also wrote that isn't one of main reason why GC failed but definitely was problem in some degree, the main reason is PS2.

I just checked like 20 games, and most common size is 2-3gb. 

I have a hard time believeing that the avg size was less than 1GB as you claim.

GC 1.5GB limit was a huge issue, and a bad hardware design choice from nintendo. It wasnt a exaggeration, or excuse, it was a real issue.
