I highly doubt they will payout the remaining balances because 1. the balances were off and 2. they lost a lot of bitcoin. It will be a nightmare to get this all corrected unless they restore the balances from a backup and agree to pay out at a loss and potentially have duplicate payouts. They will more than likely set everyone to 0 and say sorry wont happen again and hope people go back to mining with them. Sucks pretty hard too I've lost over 4btc.
