If 7% of all bitcoins really are gone then the price rise would be more like 30% because the 7% were from the actively traded float, not from the several million hoarded and locked away in Arctic-cold storage.
You seem to be forgetting that there were also a lot of fiat afloat at mtgox that was meant for BTC. BTC will lose that fiat, and probably any new fiat that would of came from those who owned it.
It's fun to see how everyone are trying to downplay the gox situation and are trying to make this look good.
I am certain that it will go back down again after this rally, but even so you are missing out on 30% profit by continuing to wait till it goes back down to the $200-$300 range? It might go back down to that price range, but I assure you it will not stay at that price point for longer than a day.
