Nintendo has confirmed that they’ll be sticking with recent tradition and not having a life press conference at E3 this year.
They’ve gone on to state in their investor’s report that they’ll be detailing their plans for E3 at a later time.
Last year, Nintendo decided to dedicate E3 to The Legend of Zelda: Breath of the Wild. They didn’t really announce anything but instead opted for smaller live streams showcasing Breath of the Wild as well as some other Nintendo titles.
