In addition to the big DLC news, Nintendo also released a patch for Zelda: Breath of the Wild today that added something fans have been asking for since the last big trailer: The option for owners of the Western version of the game to play with a Japanese vocal track.
That's now possible with a simple toggle in the game's main menu, which lets you stop playing in your system's language and play in Japanese (and also Spanish, and Italian, and German, and so on).
Note that this only applies to the game's voice acting, not in-game text.
It's a small touch, but since a load of folks think the voice acting in the Japanese version of the game sounds to be a better job than the English dub, it's also a welcome one.
For a quick and dirty comparison, here is the game's big 2017 Switch presentation trailer in English:
And here it is in Japanese:
And here's a compilation video showing the same intro sequence in all the languages you can now play in:
The patch is available now, so install it whenever you're at your Switch.
