If you're not out of Mt. Gox already, it's probably too late.
Not as long as people are still receiving their wires, and there are steady reports from people receiving their wires.
Some money does seem to be trickling out of Mt. Gox, but very slowly. That suggests it's coming from newly deposited money, and that Mt. Gox is probably broke.
Do you really think people deposit large sums of money at MtGox now, in this market? Don't think everyone receiving a wire from MtGox will come to bitcointalk.org to brag about it.
