That's what I was wondering. MtGox is at $124, the other exchanges are at about $80. Will MtGox drop to $80, or will the other exchanges jump to $120, or will they all meet around $100? I suspect there will be some arbitrage. People have been buying at the functioning exchanges in order to sell on MtGox, so either dropping to $80 or meeting at $100 seem more likely to me. No matter what happens, that should be a temporary, initial pattern.
