Other exchanges have bottomed out at about $70.
I would assume that as soon as mtgox opens the price will shoot down to $70, at which point the buying will start bringing it back to somewhere around $100.
When Gox suspended trading, people who wanted to sell at all costs could easily their bitcoins out to sell at other exchanges, lowering the price on those low volume exchanges.
People who wanted to buy cheap coins on those exchanges couldn't get their $ in as easily. The speculation threads are full of people cursing that they have no fiat on these exchanges to buy cheap
BTC.
