They said Josephine wasn't gated, so it has to be Vivienne, if it's a bisexual female.
It's interesting to note that Iron Bull was originally planned to be gated and they managed to work out the cinematics in time, according to con goers. So, there were 3 race gated LIs planned for a long time. When they released his profile, they still weren't sure if he'd be race gated. This makes me think that surely one female will be gated. They may plan two race gated males, but a possible 3? I think one is almost surely a female.
It's still possible that one of the gender-gated LI is race-gated as well. Not my favourite scenario, but Gaider said
that some gender-race combo might have less options. If the last two are bisexual and race-gated, there won't be race-gender combo will less option. There'll be race combo with less.
