During the Tenta Live performance at Tokaigi 2019, there were signs that Version 4.4.0 could be landing on Splatoon 2 very soon.
In different segments of the concert, the audience could see parts of the in-game menu, and on the menu the version of the game being played was 4.4.0. This means Nintendo has Version 4.4.0 in a working and playable state, so we could expect it to arrive very soon. The current version at this time is Version 4.3.1.
