I am a little bit confused. The statement was that they recovered some BTC200,000 from an offline wallet. At that time, Mt Gox was under a lock down. So no one could have moved the coins. At least let us hope so.
Sure, MtGox's statement was that they recovered those funds. So if you believe them then you would have to agree that MtGox still has access to those bitcoins and they are still in circulation because Karpeles could decide to spend them at any time.
To go from there to some scenario where the Japanese administrator — in contradiction to their own government's previous statements — recognises these bitcoins as assets of MtGox and decides to work out how to seize them, do so, and then auction them off, sounds to me like the height of fantasy.
But if you don't have even 0.1
BTC's worth of confidence in that theory then I don't think there's any point in us debating it further.
In summary I think the MtGox débâcle is done with and while some miracle reinvention of the company could just possibly cause some positive press that pushes the bitcoin price up a little (irrationally), I don't think there's anything negative left in it.
