I am new to the scene but lost about $150 to Gox. My gut feeling is the "leaked" doc is legit, and the numbers are believable. The timing of the site going down and the fact it has been so long since the problem surfaced with no disclosure of details the whole time makes me think there are huge losses. If the parties who exploited the malleability issue found it was possible on a small scale, then they would have done a large amount in a short period of time. Then they continued it until discovered, which could have been a while considering what we know. Then the coins in cold storage would be almost the only BTC left to try to keep going with. Maybe even while the theft continued. I doubt there is a buyer. Gox is trying to get all of Bitcoin to fix Gox and I don't see that happening. I had just been thinking if trading has continued this long, they are going to make it and I was about to buy more Gox coins. Lucky this happened first. This actually may be best because it will likely lead to bankruptcy and Bitcoin price will recover more easily, and by the time the court helps divide what remains BTC price may increase such that Gox account holders net 50% or more of the value they had before the "crisis", even after sharing the losses of the theft due to poor security. To me that looks like best case.
