I'm just excited that Vietnam appears to be coming so even if there are better options than the Trung sisters I'll be happy with whoever they decide to pick, as long as it's not Ho Chi Minh, which I doubt it would be anyway.I don’t know too much about Vietnam, but I’d personally still like to see Ngo Quyen, who unlike Trung Trac, actually successfully defeated the chinese for good and permanently established vietnam as a political entity (although he didn’t control the whole region and he didn’t call his kingdom Vietnam). He also was indubitably Vietnamese and likely spoke it or a related language.
Then again Trung Trac would probably mean no Maria the Mad and Semiramis/Shammuramat considering they usually go for 3 female leaders for every expansion/dlc cycle.

I feel like they've done a litle better job in Civ 6 such as Eleanor speaking Occitan. Though I agree I wouldn't be surprised if they wanted a Vietnamese leader to speak Vietnamese.you missed my point. My point is that I can imagine the devs using a language they didn’t speak, like when Ramses the Great spoke Arabic in civ 5.
Anyway, I’d argue the language they speak is importnat. Language is an important part of national identity.
