Mostly Norway, Sweden and Germany.
Norway - 22 quotas, currently 9 athletes selected (10 selected in 2014), will be at least 10 reallocations presumably
Sweden - 13 quotas, currently 8 selected
Germany - 16 quotas, 11 athletes reached internal standards
And then we have the likes...
Liechtenstein - 5 quotas, will not use more than 2
Netherlands - 2 quotas, will decline both
Belgium - 2 quotas, will (likely) decline both
Cayman Islands - 1 quota, both Travers brothers retired, nobody left
Denmark - 2 quotas, will decline women's quota
New Zealand - 2 quotas, will also likely decline women's quota
Japan - 6 quotas, used only 2/8 quotas in 2014, so I expect something similar
Mexico/Albania - 2 quotas, both of their female racers haven't entered a single race this season, it's questionable
And I'm pretty sure that between CAN/FIN/FRA/GBR/SLO/USA at least 2-3 more will be found
Maybe I missed some more...
All this equals 30-40 reallocations.
