In a few days time, Super Smash Bros. Ultimate will receive an update officially adding Byleth to the game alongside a number of other fixes.
Nintendo has recently put out a reminder that the update is coming, and that players should take steps to save their replay data before it arrives. As always, once Smash Ultimate has been updated, all replay data from previous versions will be incompatible.
Version 7.0.0
Ver. 7.0 of Super #SmashBrosUltimate will arrive within one week! This update will include fighter adjustments, meaning replay data from previous versions will be incompatible. Convert your replays by going to Vault -> Replays -> Replay Data -> Convert to Video, before updating.
