Do they think there are still a bunch more coins hiding away there?
The liquidation is being sorted out in Japan, presumably they will settle Japanese interests/debts first (tax man??)
They have 200,000 coins ($80,000ish?) to go around, that small sum of cash will get split between the largest creditors first and the liquidation company's fee's.
There is no money, there is no chance of more money in the future.
