The rather large community waiting in the wings about that finally got their answer. ETA on Same Gender Romance Arcs is "sometime this year"... because they want to do it right. They're not going to just tweak the dialogue slightly; They're actually writing new romance dialogues for the SGRAs.
Here's a bullet point list the SGRA thread put together
To be more precise, the SGRAs will be part of the first major story patch. When that will be, and what it will do beyond continuing the story, only Bioware knows. But I'm interested.
- They didn't expect the issue to balloon this much but they have been keeping abreast of what we have been asking.
- The initial delay over launch implementation was a matter of time and money. They went over-deadline and over-budget.
- Same-gender content is coming with story continuation, this year. So that is our ballpark ETA.
- It really is being worked on, apparently by the writing team at this stage. That's given plenty of time because it takes that long. They want to stress doing it well rather than doing it fast.
- There was no mention of new story content being tied to a retail expansion, so it looks like content patch is what we can expect.
- There was a clear indication that romances will be available for some existing companion characters, where it would be appropriate for that character. They won't say who yet.
- No mention was made regarding [Flirts] or same-gender content beside companion characters. No mention was made of a special filter option.
