Growing Awareness of China Apartment Bubble?

WSJ:

"Take a drive through China's third- and fourth-tier cities and these issues are all too visible. Many cities are ringed by row after row of empty apartment buildings that reach 20 stories into the sky. At night, they are dark save for blinking red lights on top to warn airplanes."

I don't hear anyone pretending anymore that these apartment buildings were brilliant, needed investments that will be occupied "real soon now".
