While the companies’ E3 showcase is likely focusing on the Nintendo Switch, there is also going to be news for the Nintendo 3DS. This news is compounded by this years E3 being the first time the public is allowed onto the show floor, so Nintendo will be doing something with that – what form that will take, we don’t know as of yet. The announcements of The Legend of Zelda for Wii U along with the first live game play of Pokémon Sun and Moon also showed at E3, so expect something similar in size. For those planning on seeing the usual Digital Event, plan to see something new and more exciting in the age of the Switch. Hopefully this E3 will answer further outlying questions such as the shortage of Nintendo Switches.

Reggie Fils-Aime elaborated on this saying:

E3 itself takes place from Tuesday June 13, 2017 to June 15 while Nintendo Treehouse: Live at E3! will only be on the last two days.
