There is no new batch released yet, neither English or Chinese website.
That's kinda given, since it will be released tomorrow at 11:00, (GMT+8)

Make your alarms guyz, we have camping time to do tommorow

Why are they releasing now 13.5 TH/S model instead of the 14 TH/s model they had last time?
I guess they have old used machines that they want to sell. Explains it?
Honestly i have no idea, that could be the possibility, they are upgrading their farms with 14 TH/S. I can only speculate about that question, batch before 14 TH/S was 13.5 as well
I'm pretty sure the average quality of the chips in this batch is slightly lower. This overall per machine makes them to lower the speed it will be expected to run at. They only find out after running a relevant batch of machines for a few hours, to see what results they bring.
I can agree with low quality chips thou, because i have seen a lot of topic here in last few days were people are complaining about dead boards in there, or like "bought 12, 3 is already DEAD"... Something has been very lowish quality with them then since that is happening. I only HOPE with mine everything will be alright(willing to take that risk)
