Those funds are no more. They have has ceased to be. They have expired and gone to meet Satoshi. They are late funds. They are vapor. Bereft of existence, they rest in peace. If Karpeles hadn't left them on the balance sheet, they would've been written off ages ago. They've rung down the curtain and joined the choir invisible. They are ex-funds.
They are not gone, just pining for the blockchain...
Beautiful funds, those bitcoins.
This whole matter is far from being concluded... there is a lot of sorting that still NEEDS to be done. I am sure that we DO NOT know the half of the financial situation of Mt. Gox and the extent to which it may be feasible to either reopen or to reimburse customers.... these details are going to be worked out in the coming weeks.. and maybe months.
