I know it is jumping to conclusions, but there is a lot of evidence suggesting that this crew was not well trained and able to adapt to the situation of a visual approach without GS, (read the pprune thread). Like it or not the Asian carriers have a history of only training there pilots to be computer operators, and there pilots have very little stick and rudder time.
That being said, my concern now is that we have SFO open again and heavy aircraft (many from Asian carriers), operating with only a 1R for takeoff, and 19L for landing. To me this could be a problem.
It is not just the Asian carriers...
