This really shouldn’t be too surprising. At 8pm PST next week Thursday, there will be a live Nintendo Switch presentation from Japan. The presentation itself will be in Japanese, though it will feature English voiceover for places in Europe (and most likely the United States). It is unclear if game footage and trailers should will used localized versions as well, though it’s very likely localized versions would be uploaded to YouTube and various social media outlets.
We’ll keep you updated on all the happenings for this presentation the closer we get to the event.
