Reason I continue to say Macedonia will be a yes is that Greece's bargaining power has been eroded considerably due to their...problems. Rest of Europe is going to be less likely to let Macedonia's entry be stalled due to the asinine name debate when Greece is nearing total collapse.
Perhaps, but I doubt anyone will call Greece on it publically. Realpolitik between EU member states is bad for the "project"; hell, thus far, they've been reluctant to even call out Greece on the obvious stuff.
Plus, the EU seems to give substantial deference to existing and more senior members. If it's between Macedonia and Greece, Greece wins.
