Other groups start process for full refund. There are groups with more then 60 days delay. With current difficulty trend any delay just killing the ROI. My suggestion is to go for refund after 2 weeks of delay there is no reason to wait more!
If on 16-th of September 06:00 EET (GMT+2) there is not @ least shipping info I'll ask everybody in the group to vote with signed message to go for refund or not. But @the present state about 6500 chip orders , become miner boards orders so for now most of the group voted with their wallets to go for the chips.
I think that most probably the refund if any will be done with the second batch and 1-st batch will be delivered, combining users with different wishes between both batches .
But It is 2 weeks early for that
