Lets not got ahead of ourselves here. It's likely going to come Wednesday evening, US time (previous announcement was 9pm Central Time).
Don't get fooled by the countdown to 12:0AM China time.
I believe 8 pm Central time is about 9 am the next day in China, so beginning of the work day. 9pm is certainly not within work hours (in the US).
If we don't hear anything by the end of the work day on Weds in China, then I think this thing will tank, regardless.
