However, if price rises in other exchanges, that can only be because of bitcoin demand exceeding supply. You cannot twist it anywhere.
I would therefore closely follow the pricing in Bitstamp and others, and that has been on a rise lately. It is tempting to think that the going price is $120 (Gox), but I would more likely put it at $103. If I were to buy, I would not try to send money at Gox to buy at 20% premium, I would use Bitstamp.
Bitstamp has 5k less coins in their Ask compared to 1-2 weeks ago. Most likely, they have all been move to Gox to sell.
I believe the buying pressure in Bitstamp has just consumed the coins.
Gox situation is special. I don't believe that their bid side comes from true demand, because it is so much easier to use other exchanges for buying, and their price is also much lower. To me it seems that most of Gox bids are money trying to escape Gox in the form of bitcoins.
This money is orginally as Gox-USD, and most of the owners want it converted back to USD after escaping from Gox. It does not change the total bitcoin supply-demand, because it is both originally and eventually USD. Bitcoin is therefore used only as a value transmit mechanism for Gox-USD.
