So then it is confirmed that Gox' coins will be liquidated and no BTC balances returned to the users.
The published document doesn't say anything like that. It says instead quite the contrary: an audit of company assets will be conducted, proof of claims will be filed by creditors and found company assets will be used to (at least partly) repay them.
Nobody will probably get back
everything he/she owns unless stolen/hidden money is found, but anything available will be refunded.
Why are you saying no balance will be returned to users?
Please read what I actually wrote;
"no BTC balances returned to the users.". The BTC will be converted to cash.
Q. What is expected to happen under the bankruptcy proceedings?
A. The bankruptcy trustee will implement the bankruptcy proceedings, in which the assets of
the bankrupt entity will be managed and converted into cash, the investigation of the claims,
etc. will be conducted, and if funds for a distribution are secured, the liquidating distribution
will be made.
