However, if price rises in other exchanges, that can only be because of bitcoin demand exceeding supply. You cannot twist it anywhere.
Let's assume, for the sake of argument, the Gox price rise is mainly caused by their withdrawal issues creating increased intra-gox demand for bitcoins. So much of the fuzzy "market sentiment" is still driven by that Gox ticker, it's not hard for me to imagine a scenario where all the exchanges keep creeping up on the hype of the Gox price going up, even if it did in the end turn out to be a sort of bank run fueling the Gox rocket. If that were to happen, we could also see a pretty drastic drop down when the Gox uncertainty get resolved, one way or the other.
