This is a big one, something that, in my opinion, Nintendo shouldn't do. But here it is.

A website started the rumor and it seems he's onto something. It's from a japanese blog :

"Wii U version of Zelda : Breath of the Wild cancelled ! Reason is technical problem on developpement. Decision taken by Top Management."

mazon, Biccamera等はWiiU版を削除！
There is also massive cancellation of pre-order from Amazon, Biccamera, Yamada Denki... Game no more listed on homepage.

正式報告を待っている。
Waiting for official confirmation by Nintendo "

Thing is, if you go to biccamera (it's a big retailer specialized in high tech and home appliances) and Amazon, the games have disappeared.

Let's hope that a Nintendo statement confirming otherwise will arrive soon.

Makes sense to be honest.

Doesn't really matter to me since I'm getting the Switch day 1, but that would really suck for people who don't want the Switch.

BS. Don't believe it for a second. Website shows Wii U version. They played the Wii U version at the VGAs. They keep saying for Wii U. Plus Amazon is pretty terrible at listing Nintendo products. NES classic any Amiibo and getting it wrong on some physical games.

False. It has already been shown on Wii U.

Sounds like BS, game is done and they are now just localising and testing, every time we saw Zelda we saw Wii U version of Zelda running, even this last gameplay video from game awards.

I don't think that Nintendo wants to lose all their fans trust before launching Switch. WiiU owners will be mad if it's true

Well, anything is possible, but considering that they've shown the game for WiiU recently it doesn't make much sense...

As much as I don't want to believe this, there are a lot of things we've been sure wouldn't happen that did with regards to the Wii U.

I'm usually of the mindset that Wii U owner opinions don't matter with regards to Switch, but this would be a PR catastrophe of unrivaled porportions if it were true.

Fake. The game is still on Amazon Japan.
