They learned this when they first released FC housing. Didn't matter. Same thing still happened. I'll even outline their success formula for you in case you want to go make your own AAA MMO:

1) Rush out housing because we gotta go fast! Lot's of contents in my themepark MMO!
2) Who need to spend more money and invest on new housing servers? Scrubs.
3) Housing speculation simulator 2015 (huehuehue it'll be a shy over 800k+)
4) ???
5) Profit!
