yeah, it still works from PC to N9 and from N9 to N9. Just tested it.

for PC to N9.. Like GringoT mentioned.. If you click the usual video chat icon, it'll send a link for google hangout and that doesn't work. But if you wanna initiate a video call like earlier.. In the chat window on PC, there's a drop down next to the call icons called "more". Click that, then select "Start video chat". This is the way it still works on N9.

works so far.. Till Google completely implements the hangout ****.. So start video calling!

(N9 to PC video call doesn't work. Keeps diaconnecting.)
