JM,
Yes, there have several articles on CNBC.
The Swiss removed their floor to the Euro because trying to maintain the peg was costing them a lot of money, which would only get worse when the EU started their own QE program.
Germany won't leave the Euro because it artificially keeps costs / expenses low. If Germany had their own currency, it would be valued much higher. So high that they could not compete in global trade.
Greece, here is a perfect example of a country living beyond its means until it ran out of other peoples money. They should leave the Euro, return to the drachma or something new, then devalue it and climb out of their hole. To be successful, they will have the completely change their mentality on business, employment and welfare.
