Hm. If we go by the EU-federal inner core EFTA-OTL EU-lite outer shell future path, I suspect they may well stay in EFTA. Their economic ties, after all, will already be quite well served by that arrangement, and the Brussel-Moscow comparison would be more frightening if the EU openly is a federal polity.Well, I acknowledge that it is not a sure thing, and EE may end up in the EFTA, especially if they are not yet a fit socio-economic and political shape for EU membership, but most likely it is going to be a temporary phase in the end, since in the overwhelming majority of cases, EE is still going to have stronger economic and cultural/political ties with the EU no matter what, even if they go in the EFTA first.
