maybe not, but does 3-4 months really matter?

Obviously people still expected more, and their expectations weren't met. I don't have a Wii U so I don't really care personally, but I can definitely see why some people are upset.

I said 'in an extreme case', and I said it mainly to make a point. If Zelda was one of Wii U's selling points for someone, it lost one of its selling points when it was announced that the only Zelda on Wii U would be simultaneously released on Switch as well. Obviously it's not likely that a lot of people got a Wii U just for a new Zelda games (otherwise they would've just waited, just like you said), but had they known this in advance (and looking at Nintendo's history with Zelda games, they had all the reason to anticipate an exclusive Zelda), they might have considered getting a Wii U more carefully. At the very least their expectations wouldn't have been broken.

I get it to an extent, but the thing is the game is still coming to Wiii U so that selling point is still there and if Zelda wasnt the only reason that they bought a Wii U than all those others still exist.

For example, lets say someone wanted a Wii U for these 5 games, Mario Kart, Smash Bros, Bayonetta 2, Xenoblade, Zelda. Guess what? all 5 of those games are on Wii U.

At least these people still have the option of playing the game on Wii U, its not like Final Fantasy Versus XIII or The Last Guardian where they were delayed for years, assumed to be dead, then all of a sudden showed back up and were no longer releasing on the consoles they were originally announced. 

damn then 360 and ps3 owners must feel screwed over too, with all the remasters ps4/xb1 have gotten o.O

I typically dont buy consoles at launch and wait until it has at least a few games i really want.

I bought Wii U in March or April 2014, at that point it had NSMBU, Pikmin 3, Wind Waker HD, 3D World, Tropical Freeze and Mario Kart was just around the corner. It had a handful of games i really wanted so at that point it was a worthwhile purchase and the droughts werent as big of a deal because i had enough games to keep my busy for a decent amount of time.

I guess it's mostly a matter of expectations and not meeting them. For some people, it could be a big deal, even though it seems most people take it more calmly. That's the case especially if Zelda was a big factor in the decision of getting the console.

Those two examples at the end are pretty good ones, I have to say. For the longest time I wasn't even planning to get a PS4 (or Xbox One, for that matter), and I was pretty disappointed to see those two games slide away from PS3. Now, I just recently got a PS4 so it doesn't really matter that much anymore since when getting a PS4 I think I didn't even know of those two games, but it was still disappointing to think I would miss those games (because I'm not getting a console just a for a game or two in most cases - consoles usually cost a good bit of money).

The problem is that the game was already delayed 1 full year, most likely because NX version (now Switch), and now it is delayed once again, but not confirmed to be only 3-4 months.

Latest ER rumor says that Zelda won't be at launch...

that does suck, im not gonna say it doesnt. But IMO thats why its so important to not put faith in one game to hinge on the purchase or enjoyment of an entire comment. It's just not a good idea to buy a system for a game that didnt even have a real trailer. No matter how the past systems turned out.

People are very upset, but no one can be more upset than Nintendo.

Why would the option of playing the game on Wii U matter when Zelda drops below 30fps on Wii U and has no gamepad features and the multiplayer community moves to Switch? If these ports were released in 3 years then you could make a good point, but they will be out very soon after the original Wii U releases and will have a lot of exclusive content, making the Wii U worthless.
