I hope that it is an island area, let's say atop a hill, where you can decorate the whole area with outdoor furnishings, and a more involved, new gardening system, with the ability to have some minions walk free, but I also would like a house in that island so you can decorate both the exterior of the island and the interior of your house, this way everyone can have a house (you'd have to pay to place it / expand it, so it would still be an investment). Ideally it would start as a small but you could upgrade to medium, then to large, so people would have that to work towards along with it being a gil sink. Also your friends could teleport there like they currently can with the housing system we currently have. Having this the normal housing wards could be a thing for FCs, RP venues, or for people that really like that area's aesthetics.
I think if it's not instanced housing there will be major disappointment and a lot of complains, I think the dev team is aware of that expectation.
The worst it can be is a place like the lost ark stronghold, a lot of systems and menus you have to interact with weekly to get extra rewards.
