To my knowledge SE is not making anyone wait. They stated that the marriage system will be implemented with opposite sex marriage only, so we know for certain that when it is added that is how it's going to be. Yoshida said that after it is added they would consider feedback and what not from the players and might add in same sex marriage at a later time.
So in short, same sex marriage will be the only option when the system is added into the game. Any feedback given before then will most likely fall on deaf ears since they've got other things lined up before then.
