Which will result in Greece defaulting. The debt market would still cripple Greece. Even worse than it has now. Also trade with Europe, Greece's biggest trading partner would most likely decline with Greece leaving the Euro, which would hurt Greece tremendously.
EDIT: To further expand as to why Greece would be utterly ruined. First of all, unlike previous years, the only people that would be ruined in a Greek default would be Greece. The bailouts resulted in the debts transferring from financial institutions that would have been ruined to various global financial institutions and EU governments which can handle a Greek default, but as a result new bonds that Greece would issue would be junk resulting in massive interest rates and premiums to investors. So basically, the only people hurt by a Greek default, would be Greece and its citizens. A New Drachma would need to have financial controls to prevent Greeks from moving their euros outside of Greece which would ruin economic activity within Greece. An exit from the Eurozone could lead to Greece getting kicked out of the European Union which would devastate Greece's trade capabilities. All of this would create a New Drachma that would essentially be garbage, like the German mark during the Great Depression.
You can't blame Europe for the financial recklessness of New Democracy and PASOK. Not only that but they blatantly lied to get into the Euro. The only real criticism the EU deserves is that they didn't have any teeth to punish Greece when they found out they lied and they didn't have teeth to enforce the rules.
