It really begs belief that Mt. Gox's cold wallet was completely emptied out all of a sudden? And if it has been emptied out over the years due to "malleability issues" and "double-spends", wouldn't you think that Mark would have noticed the rapidly (and mysteriously) declining cold wallet balance? So he decides to wait until now (after the media storm) for the perfect opportunity to "announce" that the cold wallet is completely empty. How long has he known this? At the very least, he has been dishonest with his customers for the past year of Mt. Gox operations.
