Gameplay changes are likely coming in this patch.
Nintendo’s newly-released Super Smash Bros. Ultimate is getting a patch sometime next week. The announcement came via the game itself, which has started alerting players about it.
The interesting thing about the alert is that it comes with a warning that any replay data from matches prior to the patch would no longer work after it. This seems to indicate that the version 1.2.0 patch will bring with it significant gameplay changes to Super Smash Bros. Ultimate.
