Tsatevich gave Russia its first win, so six countries remain:
Denmark
Kazakhstan
Poland
Portugal
South Africa
Switzerland
Denmark have Fuglsang who has at least 1 win in each of the last 4 years, Bak who had two victories last year, Breschel who won in 2012, 2010, 2009 amongst others. Hard to see Denmark not winning something sometime this year.
Kazakstan will probably had to rely on Maxim or Valentin although Dyachenko might be a chance as well. Gruzdev won the tour of Hainan last year so might do it again. I could see them going winless for the season.
Poland have Kwiatkowski who probably will win something. Even if he does not Rutkiewicz will probably win the Szlakiem Grodow Piastowskich again or another similar race. Poland will win something.
Portugal have Rui Costa who is a race winner and should get something this year as well. The Volta a Portugal also has a Portuguese stage winner every year so they will get a win there at least.
South Africa have Rienardt Janse van Rensburg as the main chance but Darryl Impey picked up two wins last year as well. Some on the MTN riders might pick up wins as well and there is african 2.2 stage races like the Tour of Rwanda which Darren Lill won last year. Still possible there will be no wins I guess.
Switerland have Cancellara and if something happens to him Albasini has won something every year since 2007. They will win something.
So after all that I think I will go as Kazakstan as the most likely to go without a win for quite a while.
