Well I respect your opinion, however, it's probably a guarantee that they will have an asari, quarian, turian... hannar that is going to be romance-able.. my advice.. don't romance aliens if you don't want it.
Everyone wins.
A guarantee that we'll see a Quarian romance? Doubtful, I don't even see Quarians being in the game, they're too weak to even be considered as part of a cross galaxy mission(now obviously we have no idea how they actually get to Andromeda until it's explained, but regardless of the way, I don't see Quarians as being an option)
Asari, obviously they're an option, they're the default bisexual romance option. Can't have a Mass Effect game without ploughing Asari, it just wouldn't be the same.
Turian, maybe, I don't see them throwing us another male Turian, so we'll likely have a female Turian, if one at all. And now we have to play the balance game to make sure all sides are equal. So doubtful it's even a romance option, having the 100% guaranteed female human option, the asari and now a female Turian, throws straight male players three options. Too many if they're going to try to keep it even all around.
