BG3 originally had 1 female Tiefling, 1 female Githyanki, 1 female Half-Elf, 1 male Elf and 2 male Humans.
Based on reactions of their fans, they added 1 male Elf and 1 female Drow.
Jaheira and Minsc dont really count because they arent romances.
Since I havent played any Divinity game, I dont know, but my impression is that previous Divinity games did not have romances. At least nobody has mentioned that there are any.
So if they have romances again, which I dont know, yes it might be by majority races that are closer to human. Not so much dwarf, halfling, gnome.
D:OS2 had romances, including romances with undead, dwarf and lizard characters. But it wasn't a romance heavy game. The success of BG3 would probably tell them that putting romances (and sex) in the shopping window brings in a wider audience and increases community engagement. I would be very surprised if they stepped away from the formula.
But I hope that they don't strictly follow the public vote and popularity. Including some unconventional romances and characters, like an imp, would be a bit of a hail mary, but if they can write a compelling and interesting character, I think it can pay off. I think that if you write the characters and stories you feel passionate about, the popularity will follow. And if you are just throwing in characters because market research says this is the hot stuff people want, they will feel unoriginal and fall flat.
