I think it is pretty obvious from the title. Boat houses. Is there any chance that we get it? Instead living in a house, I'd prefer that my character to live on a boat. And to add various crew members (hirelings from crafting skill lines) to bring you crafting mats. Maybe some daily or weekly missions, fishing missions, etc...
