nice lateral thinking 
wont happen because as the strongest economy in the eurozone germany benefits most from the single currency. a major reason they export so much is because their currency is artificially weak.
And there's the crux of the matter. Germany benefits greatly from the Union and the single currency. The Germans stand to lose quite a bit if the Euro breaks down. The bank failures that are threatened by the current states that are in trouble will also greatly hurt the Germans, as well as everyone else.
So, in the end, I expect Germany to bend a little and help bail out the troubled countries. It's really in their best interest in the end. But if they don't get the troubled countries to reform first, it will just postpone the problem.
It's really a difficult position, in my opinion.
