They confirmed that they are working on giving us the option to move housing. But they didn't tell us much about it yet, so everything is just speculations right now.

They haven't officially said they were adding Ishgard housing yet. They said they will add Ishgard housing OR add more wards to the existing housing areas. They can do both, but from what Yoshi-P said, it looks like they will only do one or the other.
