Do they not have to split up all the BTC between everyone gox owes BTC too...?
As already discussed here many times, unfortunately that is not going to happen. As a part of the liquidation process, the authorities will auction off the remaining Gox coins and convert them to fiat.
There is no real precedent to liquidating bitcoin (or other electronic currency) in a bk proceeding. It appears that the law would probably have the coins be sold, but it would not be too much of a stretch to say a new precedent could be formed.
