I don't even think MtGox is worth the 20% payout to creditors. I don't think they own any real estate or physical assets other than a few servers. The coding for the exchange is crap compared to other established exchanges. The banking relationships are suck, and MtGox didn't have anyway to send out USD deposits. And the reputation of the exchange couldn't get any worse unless it was revealed they also ran a dog fighting league. The only possible asset of MtGox is the contact information of all previous customers. That might be worth a few hundred thousand, or maybe even a million, but I can't imagine many investors wanting to pay more than that.
