Will they be refunding all the stolen bitcoins or will declare bankcruptcy ?
Well, it's nearly 2 million USD that are "supposedly" stolen here.
Last time I checked, they were running 400 BTC daily volumes and had, if my memory serves, 0.5% trading fee
==> 2 BTC/day of turnover on their end to which you have to remove employee salaries, server costs, taxes etc...
Assuming generously that they have a 1 BTC/day net profit, this means 365 BTC per year, at current prices this is not even 100k USD.
Therefore, they will never refund the bitcoins they stole for themselves.
