Nintendo announced a new Nintendo Direct tomorrow afternoon at 3PM Pacific (6PM Eastern). The main focus will be Splatoon 2 and ARMS, but there will apparently be some 3DS info as well. You can watch the stream at Nintendo.com or Twitch.tv.
As usual, I have prepared a stream-watching chatroom. Just go to the chatroom page, choose a nickname, and use the password 'vixen' to enter. I'm online now if you want to chat today.
