I've been following this very closely. It's well worth reading this article about it.

This gives you a lot of information about this. At the moment there is a lot of speculation about what will happen to the euro if Greece defaults. But we have to see who wins the next election next month first. A really huge problem is that trust has been lost in the Greek banking system and as of yesterday, it was reported in the FT that 1 billion euros has been withdrawn by Greek business from Greek banks and put into more safe areas such as Germany. The Russians are unwilling to lend more money to Cyprus, so if they are bankrupted by the Greeks defaulting, then where will they turn to? There is always the option of a bail out from the Eurozone but then the austerity measures will be applied to Cyprus, and it would most likely signal an end to favourable taxation in certain areas.
It's unlikely that Cyprus would leave the Euro. It would be suicidal at this stage. But, as is being speculated on at the moment, if Greece does leave, it may well spark mistrust in the Spanish, Portuguese and Italian banks, which could have a knock on effect of more Euro transfers from those banks to what would be perceived as the safer German euro which would not devalue if the Euro is abandoned. At the moment, if Greece left, the Drachma would initially be launched at a rate of 1 to the Euro but would quickly devalue to at least 50 times less than that.
So in all, I'd say watch what happens with the Greek elections and if the worst does happen and it leaves the Euro and defaults on its loans, then keep an eye on what's happening to the Spanish and Italian banking systems. Also the Euro rate will be affected because of the uncertainty surrounding the smoothness of the transition. Right now is not a sensible time to be changing extremely large sums of money into Euros. Wait and see.
