It seems that, according to The Slog, despite all public statement to the contrary Berlin (ie Chancellor Merkel) has drawn up a plan to keep Greece in the Eurozone at all costs:
"Merkel has decided to go all out for her Fiskal Pakt and keep France on board by bribing Greece to vote yes to the Eurozone and the Troika."
In other words the Greeks will have their cake and eat it.
