MtGox Creditor Meeting PDF and Overview
Koyabashi has gone from 14 outstanding disputed claims valued at us$45 million to 3 in the last 6 months. Its likely these will be settled in next 6 months at which point all the legal disputes over claims will finally be over.
There has been no progress on the legal question of whether or not distribution in BTC as opposed to cash is possible. After 4 years, I am flat out astonished that this question has not been answered.
Koyabashi has sold enough Bitcoin to make an interim distribution that matches all existing approved claims. Even if the price of BTC were to fall to zero, all approved claims are now matched by cash.
