Agreed, just a matter of time. The bigger question is that the first domino to fall?

Signs point to a mass collapse as @meyrep says, the derivatives (basically bad debts onsold & various other scams eg paper-gold) will fall one after another imho.

Nett result is a global market crash, with a massive rise in gold/silver (the money has to go somewhere) and the new kid on the block, BTC which wasn't really an option for parking money back in 2008.
