Forget about the Euro dissolving in the safe, it will dissolve as a currency before then. The entire European Union will fall apart soon the rate they are going. Greece is bankrupt, with Turkey not far behind. Germany doesn't want to keep supporting them and England is falling apart. It's becoming more economically feasable for the EU to seperate than stay together.
You forgot to include Ireland, Portugal and Spain on the "bankrupt or damn near" list. That does leave Germany, France and the UK as the main financial stalwarts, but even the UK is in trouble. As Maggie said, at some point, Socialists run out of other peoples' money to tax. At this point the French have a huge stake in seeing that the EU remains, even if as a shadow or hollow shell. It is their last, best chance at pretending they still matter in this world, so they will prop it up best they can - for a while.
The order of failure is a crap shoot at this point, although the Chinese bailing out of t-bills is a rather bad sign for us, gives more credence to the 2012 timeline for failure than the 2013 time frame I originally thought.
