Unfortunately MtGox will be DDOS'd, and the price will go back to 100'ish. This is what has happened the entire couple week(s) now. I doubt it will go to 150 this month, maybe next month. Or if there is no attack on the biggest exchange.
Or more exchanges come online to give Mt.Gox a bit more competition.
Funnily enough, all of Gox's competition seems to be ending up closed due to hacks, "hacks", regulatory problems or bankruptcy.
I'm just sayin'....
