There's nothing supporting speculation that Gox is bankrupt or otherwise out of fiat. It more likely can't transfer fiat because they're either unwilling or unable to work with the conventional banking structures to push out the volume they need.

Not being able to send out fiat (particularly bad with USD), volume is obviously dropping, because even though the price is higher, what good is GoxUSD if you can't redeem it for real USD?

Gox is dying (really, 0% chance of ever recovering the majority exchange market share - so "dead" might be appropriate), but I don't see anything suggesting there will be some type of destructive implosion (outside a severe lack of urgency @ Gox to resolve this).
