Nintendo's press conference will wrap up the briefings for this year's E3, but that doesn't mean it's going to be lacking. We're expecting to see more about Super Smash Bros. for Switch and Let's Go, Pikachu and Eevee during the conference. On the floor, Nintendo will host two tournaments for the new Super Smash Bros. and Splatoon 2, and hand out special collectible pins to attendees who bring a Switch along.

We're not exactly sure what other surprises Nintendo will have in store this year, but there are plenty of rumors already. We hope to see more on Metroid Prime 4 and Yoshi, both of which were teased at last year's show.
