South Korean Youtube personality Large Library TV (buzzbean11) has announced a special Nintendo Switch broadcast set to go live on July 21, 2018 at 11pm Korean Time.

During the broadcast, games such as Mario Tennis Aces, Mario Kart 8 Deluxe, and ARMS will be played and streamed live.

Large Library TV appears to be a very important person in South Korea (he has 1.7 million subscribers) as Nintendo Korea actually promoted the announcement of the broadcast on their official website, so this may very well be something sponsored by them.
