Square Enix confirmed the marriage system to come in a future update, but they had some interesting responses for fan questions.
Naoki Yoshida, one of the directors, said that he is open to the idea of same-sex marriages within the game, however Square Enix are still discussing things with themselves and the players and are yet to come to a final decision about the sensitive topic.

Yoshida also managed to answer some other interesting questions, such as the possibility of new races and clans and about the new housing features. You can read the full transcript here, or check out this video:
