A collapse of one sort or another is inevitable sadly IMHO. It's just a question of timing and scale. Once again we've seen markets rise due to the Greek vote but I doubt these fluctations will last or represent anything other than the sort of short term trading opportunities we've seen all too often when the greater of two perceived evils has been avoided (for now).

I believe the best we can hope for now is some form of managed restructuring of the Eurozone and a great deal of economic pain but given the intransigence and denial evident amongst the Eurocrats I doubt we'll get even that anytime soon.
