This hasn't made it to the mainstream American press yet, but the gist of the situation is that, while Germany hasn't made any official announcement of intent to leave the Eurozone, they are reportedly printing their old currency notes. In a hurry.
The Germans are no fools: they know better than anyone in Europe what happens during economic hardship - it was the fiscal cratering after WWI that set the stage for the rise of Adolf Hitler and WWII. Based on that experience, they are very likely to vote with their feet and pull out of the Eurozone. When that happens, the inevitable collapse turns into the imminent collapse.
