Don't hold your breath.
Anyone who gets back any of their lost money should consider themselves very lucky.
Right now only luck can help them. Regaining what they lost is something very big, because the reputation they gained as a trusted platform and in the top list won't be retained back. Possibly it won't be sought out in a short time of within a week or too, I believe it would take months to solve the issue.
Bitfinex's first plan is to look for banks that are willing to do business with them, without actually registering their activities in a proper manner. It's something they till now haven't done.
If they took the effort to do so, this problem wouldn't exist, but there surely must be a reason for not doing so. It's Bitfinex after all. Nothing happens without a reason.
If they want to continue along the same lines, they must find a bank from some sort of an island to be willing to offer their services to Bitfinex, but without them willing to register themselves properly, I even can't see this become reality.
