Wells, this upcoming update in GMS is going to be all the Adventurer revamps + PvP rolled up into one patch. Or so the update page (aka another silly YouTube video) makes it seem. Anyways it's probably going to be on the 24th.
Huge updates tend to be in the summer and winter, so that means Tempest is bound to start at the end of November / early-mid December.
Judging by class releases last year (Cannoneer, Mercedes, Demon Slayer) and the year before that (Battle Mage / Wild Hunter, Mechanic. Although this might have been two years ago, I can't be sure), I'm willing to bet that Luminous will be early-mid December, Kaiser will be mid-late December, and Angelic Burster will be early January.
Heh, that's funny. Mechs, Demon Slayers, and Bursters all being released at the same general time of the year, each being overpowered for their time.
Looks like they're aiming for: PvP and Legend/Explorer Revamps: September MesoRangers, Kaede Castle, Theme Park, Chaos Pink Bean, Resistance Revamp: October Luminous: November Tempest: December; hopefully in fewer patches because that entire event was underwhelming.
