For easy reference, I'm going to post the few official quotes we have on the subject.
In September 2011, Stephen Reid made the following statements and clarifications:
Due to the design constraints of a fully voiced MMO of this scale and size, many choices had to be made as to the launch and post-launch feature set. Same gender romances with companion characters in Star Wars: The Old Republic will be a post-launch feature. Because The Old Republic is an MMO, the game will live on through content expansions which allow us to include content and features that could not be included at launch, including the addition of more companion characters who will have additional romance options.
First of all, this is definitely not an audience that consists of a 'couple of people' and we're aware of that. We take this decision very seriously.
Second, it's very important to realize that this is just one of many, many content additions that will be going into the game post launch. The vast majority of our content will be of interest to the vast majority of our potential audience.
However, one of the amazing things about MMOs is that over time we can get to add things that are exciting and interesting to smaller audiences. Normally, that's not something that's addressed too far ahead of time. In this case, we felt the addition was warranted and should be addressed early.
There will be plenty of content for all to play and enjoy.
We can't guarantee that a character you play at launch would have romance options 'unlocked' for an existing companion. It's something that will be taken into consideration when making design decisions. Not a promise it'll happen, but we'll take that feedback and relay it through to design.
We fully intend to do justice to the story in our storylines.
As you may have heard, we take story very seriously - this included.
Lastly for those of you who seem concerned that you will be 'tricked' into any romance arc in the game - all romance choices are clearly marked. You will be aware you're making those choices as you make them.
In the time between that and the Guild Summit, the only communication on the subject came from Customer Support to individual inquiries.
At the Guild Summit, Daniel Erickson elaborated on the inclusion of SGRAs, with the most important new information being that this content will come during the year 2012.
This following quote is merely a summary of what Daniel said. The full transcript will be available once the videos of the Guild Summit are available online.
Q: Any update on same gender romance?
Daniel Erickson: It is coming and it is coming with story updates. It is something that depends on the writers and we want to do right, and writers have a long lead time. We did not want to just change all the dialogue for the other gender. That is not writing, that is not story telling. This was cut originally because of budget and time issues. We have designs, we know what romance options we want to put in for this. It is coming when full story comes, and full story is coming this year. We are still on track.
