I suppose it was inevitable!
The Repopulation is adding player housing when it finally goes full release, but it won't just be instanced housing, like EverQuest 2 or its kin. They're rolling out all three versions - instanced housing, persistent world housing (Star Wars Galaxies' buildings), and player city housing (SWG's player cities).
If you want to read how they're going to do this incredible thing, they have detailed everything in a huge new blog post on the site. Long read, but worthwhile.
