Re: New Mt Gox Press Release - Feb 10 - they are claiming flaw in bitcoin protocol !
People's decision to sell (at 120 USD at BTC-e for example) was a perfectly decentralised decision. No one else was forced to buy or transact at such valuations! 
I don't think he decided to sell @ 120 USD. Here, some BTC nouveau riche just has learnt what "market order" means, I guess.
