I am once again reminding everyone that we the players asked for housing demolition, because we had entirely dead neighborhoods owned by FCs with no one left in them except the last person who unsubbed without leaving the FC first. (The 45 days was SE's mean decision. 90-120 days would have been a lot better.)

Anyway, I suspect Sharlayan is the next housing area actually. 1. The district is visible from Old Sharlayan already and 2. An NPC talks excitedly about how they are building her a house in that district.

Probably in 8.0.
