Another winner has been crowned. ZeRo is the winner of the Super Smash Bros. Invitational 2018. Sakurai was on stage to present the trophy. Afterwards, he gave a speech. It turns out that Sakurai is going back to Japan tonight to continue to work on the game. Sakurai said that he “found two or three bugs” during the tournament, and talked about balancing and tweaking the game. The balancing comments may have been in response to how Bayonetta played during the tournament. Nevertheless, there was no character reveals during the tournament.
