Considering that Mtgox hasn't processed any USD withdrawals for over a month and Karpeles is simply lying about that suggests to me that there are serious, serious issues at Mtgox. I wouldn't be surprised if Karpeles takes the money and runs.
Due to recent changes in Gox's BTC withdraw protocols (now sometimes requiring "verification"), it is quite obvious that Gox is implementing flow of funds control measures.
yes and they registered with fincen recently... he cannot take the money and run because you know there are a few wise guys that would be looking for him, and a large white man in asia is pretty easy to spot...
