You won’t have to wait until then to check out the patch, however. Game Update 5.9.2 is up on the public test server right now for any who would like to put it through its paces.
The patch is primarily focused on PvP, with a new 4v4 arena map that uses Mandalore’s Battle Ring, Season 9 rewards, better PvP matchmaking, and multiple warzone improvements. Housing addicts can move into the Rishi Hideout stronghold, which is a tropical bungalow that offers players the opportunity to host their own PvP battles in that instance.
This is the 10th update to follow the Eternal Throne and Fallen Empire expansions.
