So you're going to "rollback" those who have already withdrawn to their personal wallet then?

Some people who withdrew to their wallets still have enough to cover their withdrawal in their account. For example, if I had 1000 bitcoins, made another 2000 bitcoins during the crash, then withdrew 500, after the rollback, I'll have 500 left. (The original 1000 - the 500 I've withdrawn).
Some peoples' accounts might be 'negative' because of withdrawals. Mt gox will have to cover these losses if the users don't return the funds. I'm sure it isn't that much.
I'm sorry but this is a laughable solution in my opinion. Mt. Gox needs to cut their losses and compensate this alleged owner of the original alleged user account that was allegedly compromised.
If you expect people to take Mt. Gox seriously when their account balances go negative, then you're just as crazy. Mt. Gox does not control the exchange rate and they will no longer be a central exchange. They cannot dictate market value of the BTC any longer. What sort of accuracy can we expect from a rollback? I mean honestly.
