We actually did the math on this not too long ago. There are 4 320 available plots in all four wards. Even if you take FCs into consideration and even if you would have unlocked housing from day one - There still would be plenty of plots left. Heck, Spriggan doesn't even have so many active players. Look at Louisoix for example - They have housing since day 1 and until today it never happened that all plots were sold out. So it is basically just dragging it along without real purpose. Even if they unlock housing right now there will be plenty of plots left in months to come.
