Jin mentioned a character from his father's name and Sun mentioned a character from her mother's, but I'm disregarding that right now. And no, I don't think that the writers would name him/her "Ho." I also find it funny that "Ho" means goodness.
Also, I vote female. She can hook up with Aaron. And I wouldn't mind seeing her being named "Shin." It means "belief" which is a major theme of the show. If the baby is a boy, I vote "Jin Jr." They can call him JJ - like the writer. Okay. I'm done talking now.
I think it will be a female too but for no reason in particular.
Whichever sex it is the baby/child is going to be absolutely beautiful!
I'm going to guess that the name will have something to do with a family member of Sun and/or Jin like they said when they were talking about it being a boy and using a character from his fathers name.
I think the baby will be female. There will happen something very dramatic again so that Jack won´t be able to deliver the child. Kate will have to do it again and the girl - at least with second name - will be named Kate.
