I find the market reaction to the news very interesting: judging by the price increase on Gox, BTC is apparently accepted as a "safe-haven" in this particular situation - and BTC being considered a "safe-haven" is quite novel and interesting. It means that many of the advantages of BTC are so obvious to the buyers (free movement of funds, no freezing, etc.) that they outweigh the risks (volatility, etc.). A sign of some maturity, perhaps?
My impression is that people are buying BTC purely so that they can move their money out of Gox, and that once withdrawn, those bitcoins are getting deposited straight into another exchange to be sold. Just as the price at Mt. Gox has been going up since this announcement (due to a glut of immovable USD), the price at Bitstamp has been going down (due to people's dry powder being trapped on Gox).
