Just as a thought... Maybe the statements are not contradictory at all.
When Swen mentioned during the last stream that DOS is not a bioware game, maybe he meant that you have no romance options with other NPC's - but you can still have some kind of a relationship going on between your character 1 and your character 2.
Yes, that is possible. Or it also could be an allusion, that we will not see any sex cut-scenes, as it does bioware.
