Given the amount of complaints lately and the striking similarities with fiat withdrawals, it's probably not a far fetched idea to say that they are insolvent at all.

You're more likely to get an answer from them if you posted on their reddit, or twitter. I doubt that anyone still actively monitors bitcointalk from their end. But I reckon the only thing you are able to do at this point is just wait, and hope for the best. I think they're likely still return your funds, but time is a factor.

I would certainly warn against all users who are looking to use bitfinex presently and in the future, you're taking on a risk that they are indeed insolvent and have to deal with constant fiat withdrawal and deposit delays.
