700+ after mtgox allows withdraws then down to 600 area again after some mtgox users sell... Then settle in the 600-700 range for a few weeks. After that i have no idea.
I think that's unrealistically optimistic, even if gox survives this. I think Matt and others who expect $380ish soon are much closer. I'm buying in at $400, come what may. If it doesn't get there oh well, I was wrong.
