On June 11-12 in Los Angeles, an invited group of players will gather to play Super Smash Bros., and qualified teams will compete in Splatoon 2, as Nintendo hosts an event featuring high-level gameplay on these two games for Nintendo Switch. This will be the first-ever exhibition tournament featuring the recently announced Super Smash Bros. game coming to Nintendo Switch in 2018. Additionally, this will be the first world championship for Splatoon 2 after the game’s launch. The gathering will be a celebration of fun for all ages, and will highlight Nintendo’s unique approach to competitive play. The event will be just one of Nintendo’s activities at the E3 video game trade show, which runs June 12-14 at the Los Angeles Convention Center. Additional details about Nintendo’s E3 plans will be announced at a later time.
On March 8th Nintendo had officially teased Super Smash Bros for the Nintendo Switch,  but we still do not know if it’s going to be a port or a brand new game. We’ll most likely find out before the invitational begins in June.
