Yoshida's one sneaky guy, I know how he is. I'm going to predict right here and right now that we'll have male Viera by this time next year. I don't think it's something they want to show off for 6.0. The Viera/Hrothgar race are features of Shadowbringers, it feels kinda redundant/weird to re-announce the race again in 6.0. They'll most likely just hire a handful of highly skilled 3D artists, maybe from other Japanese companies like Nintendo, Capcom, or even Namco to work on the missing genders.

Notice how he says what's holding them back is finding a solution and not really "we need more time to remodel the gear on male VIera/female Hrothgar." A solution sounds more like needing the green-light from the shareholders to approve hiring contractors for this 1 year (or 2 year project). If let's say 3 or 4 3D artists spend that whole year remodeling gear to the specifications of the 2 missing genders that could easily be done in 1 year. The reason it took them 2 years with female Viera/male Hrothgar is because their Full time 3D artists had to work on everything from new npc gear, current expansion gear, and future expansion gear.

But see where I'm going here, if a contractor's full time job is just remodling gear for 1 year...that's very doable. It's the perfect solution because it doesn't take away from the game's resources, it also allows them to release the 2 new races within Shadowbringer's lifetime, giving the game a shot in the arm at the 1 year mark which is usually when sub numbers go down. We're all grown ups here, we know this is just theory and guesses but the possibility is there if you followed through the reading. In my eyes I see 6.0 being free to work on its own, that's just how I see it. Yoshida could've easily just said "we'd need more time to bring the missing genders if they were to be added." But instead of that he said "we need to find a solution." A solution just implies something deeper and more immediate, to me anyways.

Any thoughts/ideas on what the solution is would be welcomed.
