In today's announcement there is no timeline for the return of clients' funds.
I have been holding the WBX Bitcoins in an offsite account, for safekeeping. They're all accounted for, and are available to withdraw right now for users with BTC balances. I transfer them back to the WBX wallet as and when they're needed.
The server emails me when it's short of Bitcoins, so if there's ever a delay with your BTC withdrawal, it's because the server wallet was emptied and is waiting for me to transfer more in from the offsite wallet.
This is something I was doing for Andre rather than leaving them on the WBX server, in an attempt to prevent a Linode style theft.
