they refunded/creditied me my unpaid withdrawals in about an hour from contacting them.
I find it very interesting that MtGox support is totally useless and give copypaste answers when asking about USD withdraws. If you just ask them if canceling a withdraw is possible then they go ahead and do it almost immediately if even if you just asked if it's an option and did not specifically ask them to do it. They seem
very eager to have customers/suckers buy their over-priced BTC instead of sending them their USD.
After this much time has elapsed with so little tangible (and truthful) information out of Mt.Gox, it is fair to speculate they are in a death spiral. If this is the case, focusing on customers would be close to their very last priority. Once they have your money, you are all but a future annoyance to them until this all blows up.
That they said nothing on the now World-renowned fiat withdrawal issue is extremely telling and scary. I would get out now at any cost through Bitcoins, however each unfortunate individual who has funds held hostage by Mt.Gox will have to make that decision for themselves. If they wait too long, they could wind up with absolutely nothing.
Praying would be a good idea now.
