Actually most Russian politicans secretly dream about joining EU and Eurozone but will never admit it because Russia simply cannot allow itself to beg and stand in line for membership. It would be too much humilation for national pride. So I guess in the nearby 50 years Russia will keep pretending that we aren't interested in any EU or Eurozone participation. Also Prokhorov is a clown, don't take him seriously. He is most famous for two cases: first, when he brought some 50 whores to Courchevel and French police accused him for pimping but his lawyers proved that he brought all of them for himself. And second when he proposed a law to replace current 40-hours working week in Russia with 60-hours one.
