Things change, the staff changes, number of people employed to work on projects, funding, etc. I'd like to see same sex relationships included sooner than later, but I'm also aware of the changes that have happened to BioWare Austin the past year that have affected their plans.
This expansion is set for a Spring 2013 release but there may be a delay, who knows. Right now, at this point in time, that's the time period they hope it's released. Maybe it'll happen, maybe it won't.
I'm patient enough to see what becomes of it.
