There are so many scenarios floating around re the future of the Eurozone and the EU.
One thought of mine:
If the EU does indeed dis-integrate, then exporter economies, members of the EU (eg Germany and the Netherlands) can most probably kiss intra-European trade goodbye!
Yes, they can still rely on WTO based trade for intra-European trade! Right. See what is happening with the pro-free trade G20! Pro free trade rhetoric, protectionist measures and barriers.
