Super Smash Bros. Ultimate has been released less than a week ago worldwide, but it seems like some changes are coming to the game very soon.

Earlier today, players have been notified in the game itself that a new update will be released sometime next week. The notification also suggests players who don’t want to lose their replay data to convert it to video as soon as possible, hinting at the fact that some balance changes may be included in the update.
