It's been asked and talked about multiple times, but no definite answer can be given just in the same way that no definite answer can be given on if or when we will ever actually see our FT money again, if ever. I, personally, think that those transactions will never go through, at least for the US players, because when/if a deal is finally made between the DoJ(regarding the banks) and FT, I am 99% sure it will be made for a one-way transaction, just like how Stars was. You can get your money out, then go away. They won't allow FT to cash in on the fact that they were doing something "illegal" just so that they can make good on those Quick Deposits as it is FT's fault that they gave the money up front without confirming the deposit in the first place.
Now one thing that I do think will happen, is that those players that had the Quick Deposit go through without the actual debit from their account, will have that amount subtracted from what is in their accounts and only be able to withdrawal to that amount, which, in my opinion is fair(er). If they lost all of their free money, then they won't be further charged for it as once again it's FT's own fault. That's how I think it will go down, but once again... you haven't gotten a definite answer because it's all speculation right now.
