On 7th July attendees at Japan Expo in Paris had the chance to attend a Legend of Zelda Masterclass given by series producer Eiji Aonuma, Breath of the Wild artistic director Satoru Takizawa, and "Battle of Ganon" illustrator Yusuke Nakano. The video of the presentation popped up on Nintendo France's channel a little while later, but without captions or translations.
Thankfully it's started to make its way into other regional channels at long last, so you can catch up with everything that was said at the event. To see it in English below, for example, you need to turn on Subtitles / Closed Captions and then choose 'English' in settings.
It's an interesting watch, and provides a further reminder of why so many of us love the series and also its latest entry on Switch and Wii U.
