We have been asking for more housing and the option to have instanced house ad nauseum since housing was released with only 8 wards and no subdivisions and no automatic generation of wards as they were needed, which was promised when housing was being introduced and like oh so many things, never spoken of again after it wasn't implemented. One of those reasons to not believe anything you hear until you see it in the actual game and also the reason they are so tight lipped these days.

Just gotta face facts, they will add wards every now and then, but they are not in any rush and do not really care if you have feedback about it cause their mind is made up. Its low priority. Each patch seems massive but they are getting progressively less meaty and with the story line coming to an end likely in 6.x, who knows what they will do with the game as a whole after. Especially after Yoshida moves on, which will also likely be at the same time, he has already said as much.
