Isn't it safe to assume more wards have to be added?

The Shadowbringers site updated on April 11th. In the section about the restoration of the Holy See it says we will get a new area/ neighborhood/ district depending on the translations (in all but the English translation). (translations courtesy of Google translate)

None of that sounds like adding a housing district to me. It sounds more like just adding a new section to the city, such as a Jeweled Crozier.

It wouldn't make sense for a new district reserved as housing for foreigner adventurers to be embraced as any sort of positive symbol by the residents of Ishgard,

I don't doubt that there is some sort of housing planned. That comment during the NA FanFest was pretty pointed. I just don't think that page on the expac website is referring to it.
