Unfortunately, we just have to wait and see what happens. Unless the Sydney Consulate willingly decides to conduct interviews for cancelled DV cases in September, our only hope is that the lawsuits achieve a preservation of visas for issuance past the Sept. 30 deadline.
The Judge seems to be aware of the impacts on DV2021 selectees over the past year (~10% of visas issued so far), so I'm fairly optimistic he will issue an order which will hopefully benefit all of us.
Until then, all we can do is wait. I'm sure things will turn out well for all of us
