Nintendo has posted their schedule for this year’s Electronic Entertainment Expo, per their usual E3 Page on the Official site. As with the last several years, Nintendo has opted to skip hosting a keynote, in favor of a Nintendo Direct that will air at 9am PT/11am CT/12pm ET on June 13, 2017. Once that is finished, the Nintendo Treehouse will air each day of the show, spotlighting the Nintendo Switch, Nintendo 3DS, the new Nintendo 2DS XL (most likely), and many of the new games and titles being shown.
Nintendo will also be hosting two tournaments. On June 13, the 2017 Splatoon 2 World Inkling Invitational will begin, with squads of players from around the world competing. The next day, the first ARMS Open Invitational will be held. Both tournaments will be available for streaming online.
