The answers will all be in the hands of the new owners, but most likely:

1. No, they won't buy back. There's no benefit for them because the company is going to be basically shelved and inactive. Setting up and executing a selling facility for unmarketable parcels has costs that aren't justified. It's cheaper to keep holders on the books.
2. There won't be an opening to dump on. The company has no assets, no staff, and no business. It's a shell.
3. Once the restructure is done, the next step is probably to remove the stock from official quotation.
4. The most likely future prospect is that the company will emerge off the shelf one day in a blaze of recapitalisation as a total new venture. No telling how long before that happens. As a shareholder you might be invited to tip in some capital under a share purchase plan.

If you don't like this story, you can sell your shares to delisted.com. You will have to pay their administrative costs (say, $151). They will buy all your shares for a peppercorn fee (say, $1). You then get the ability to write off your capital loss for (hopefully) more than the $150 net fee you paid. They accumulate shares in shell companies for effectively nothing, and cash in if the shares eventually reappear on the market.
