This discussion is bordering on the bizarre- seriously, people think that wanting subtitles and the original voice acting makes you an "uncultured anime fan"?
Firstly, anime is basically the only form of TV and cinema that is constantly dubbed, to it's detriment- with less of a dubbing obsession, anime could be much more popular and well respected in the west. I mean, even a film like Your Name, which isn't a kids film, didn't come west until there was a dubbed version. This is totally unheard of in any other world cinema, besides really populist kung fu/horror flicks. This is also why Hollywood now remakes popular pieces of world cinema; no-one likes dubs.
Secondly- why are videogames any different to world cinema? I want to hear the original dialogue because it's the original dialogue. It's closest to the original intent of the designers, the Japanese actors will have been chosen by the designers rather than localisation teams, and it shows respect to the original performers, and to the fact that not all artforms have to be specifically adapted for English-language audiences. Also- listen to the English dubs for Ghibli films. Some characters become entirely different in the dub; a good example is Jiji from Kiki's Delivery Service.
And I think the important thing here is that Zelda is specifically Japenese. It's not like I played Life is Strange in French or something, because that game was set in the US and made for an American audience. But Breath in the Wild's whole visual design is based on Japanese art styles, and is the sort of game that could only come out of Japan.
If you don't think the original language adds anything to a product of a certain culture, well, I'm not sure what I can say. But good luck with cinema, because most of the best films ever made don't have any English spoken in them whatsoever. Imagine asking for a dub of The Seventh Seal or Tokyo Story or Stalker. People would laugh in your face.
I mean, I won't cry about the fact that I won't be able to play Zelda with the original voice acting, but it's a disappointment for sure. With regards to the 'learning Japanese' thing- yeah, of course hearing Japanese will help, if you're already learning Japanese via other methods. But unless perhaps you're a small child and you're hearing Japanese all the time, video games aren't going to help you actually learn the language whatsoever.
