please note that the reasons for their disappearance and the exact number of bitcoins which disappeared is still under investigation and that the above figures may still change depending on the results of the investigation.
This caught my eye...
1. They call it "disappearance" instead of stolen.
2. They kept a window to further "adjust" the figures in the future...
This, to me... feels like they know a LOT more than they are telling us. Either because they are forbidden to disclose / gagged, or maybe financial reasons etc. I think that this "investigation" that is going on has to do with freezing gox's assets (in this case BTCs).
