I was chatting with two members of Gox support earlier. They said there will be an announcement today (sorry i don't have a screenshot). I asked them was it bad news i.e. exchange closing / liquidity problems. They said no, not at all, they just needed people to be patient.

They said it was a 100% technical issue, a "dust problem" whatever that means.

I asked if Mark K could reproduce the "trick" he did one other time to prove they were solvent i.e. move a heap of BTC between two internal wallets so we know they have the coins. The support guy didn't commit to doing it but said it would be raised with Mark K.

I guess we can only wait and see.
