Gox's prices are off market because the market @ Mt. Gox is pricing in the fact that you can't cash out on that exchange. This happened to CampBX as well once they stopped ACH/WIRE withdraws. They were usually near bitstamp/btce/bitfinex/etc but once this occurred the price diverged from all the other venues where you can cash out. But you are correct, in that Mt. Gox prices are now entirely 100% fantasy because nobody can cash out anything.
