Basically it means the corporate is not bankrupt (not just yet) but it has a lack of liquidity that makes it impossible to fulfil its debts in the short term. It then gains some time to solve the liquidity problem (by selling some assets, recovering pending debts, etc) so that it can restart its normal operation... or not, and then it files definitive bankruptcy.
Sure but this is unlikely gox' situation: their whole is apparently massive, and their assets are near zero.Of course I might be mistaken...
Yep... apparently. Unless one of those theories like the one about the 200K BTC on accounts used on the 2011 showoff prove to be right, or who knows what.
Until Mtgox publish (at least to those legitimate parties) its detailed internal accounting, including the list of all the cold wallet addresses used over all these years, we won't know for sure.
