If the court decides I should be paid out in USD more than my USD balance at Bitfloor, I might try to refuse or return the part of the settlement that is above and beyond my USD balance, on the basis that I will not knowingly accept stolen property (and any USD settlement beyond my USD balance would necessarily have been stolen from other users who had predominantly USD balances at Bitfloor).
My bet is that everyone with funds at Bitfloor will end up with a pro rata share of the total "deposits", with BTC valued at today or yesterday's average USD exchange rate. And court fees, attorney fees, accountant fees, trustee's fees, and all of the rest come out first.
So a pretty good outcome would probably look like 25% of your total deposits (assuming, overall, that half of the value deposited was BTC (which is now gone) and half was USD, and half of what's left gets spent on the friction of litigation), and you'll probably get it in 12-18 months.
This is why we can't have nice things.
