few independent people in chengdu and shenzen are confirming that they are clearing there D3 batch 1 week after there previous sale because they will start taking pre-orders of D3+ soon similar chips as innosilicon
Edit: thats why the batch is crypto only, the 30ghs D3+ batch will be priced at $2199.00 come september (not sure if people in slack speculating or real sources)
Could be just a rumor to get people to not buy this batch, so it leaves more for the rest, There will be a new d3 but it wont be this quick and will be a long wait.
