I wouldn't think that they have abandoned their plans to include it. I'm sure they are working on it, but there are more pressing matters that require more attention atm, like rated WZs, Group Finder, additional content, etc.
And I wouldn't hold your breath waiting for same sex romance options with existing companions. They will probably introduce that with new companions down the road with an expansion or something.
I highly doubt they have abandoned the idea because of some minor backlash from the conservative community. Just look at their previous games for example. Both dragon age games and the mass effect games had same sex romance options. Even the original KOTOR touched on the subject with Juhani and fem Revan.
