Chiming in again because while I'm disappointed we don't have both races fully for the Shadowbringers release, someone else articulated what they think is going on and going to happen better than I could and I'd like to share.
Source is
here, but quoting:
"I would also point out that adding the opposite genders is not the same as adding a new race, were the C-level to get uppity about how the set we’re getting for 5.0 was meant to be the last new races - the races, at that point, would be in the game, so they wouldn’t be new races, technically (and in this industry, if you have to use a technicality, fucking use it)."
This isn't a very patient fandom, and I know there are contrarians who will be feeling smug about people not getting something they were excited for. But I think this is going to be like 1.0 Miqo'te and Roegadyns where they unlock later.
Also, as someone who was not enthusiastic about a more beastlike/feline race--at the very least I want to say I'm glad the people who
were hoping for a more beastlike race get to play that. No sarcasm or anything, I get that games like WoW have options for this and FFXIV has been super humanoid by comparison. I hope this ends up being the aesthetic of your dreams.
I still plan to mess around and see what aesthetics the new races are capable of.
