For Korea it seems we will be represented only in two sports again.
Cross Country: according to current status it is 2 quotas (1 male and 1 female), i think we will have one more male. Kresimir Crnkovic just has to do two more decent races until end of January 2018, and he will have A standard and as Dadic is within Top 300 it means another quota. In ladies Skender i think has no chance to reach A standard, which would give us another quota.
Alpine: currently only 4 quoatas (2 male and 2 female), but i guess this will change after reallocation. Istok Rodes did some good resluts in AC recently which should move him up significantly in the Allocation list. Natko next year should have injured status, which means he will be in Top 30 in AC and hopefully he can keep that until January. Overall i guess it will be at least 6 quoata or up to 8. Of course a lot will depend on results next season.
In other sports it is going to be very diffcult.
Biathlon: Crnkovic still has a chance, he is fighting against Japan and Poland for the remaining 4 places, maybe Great Britan and South Korea can join that fight. Two places are already gone (Belguim and South Korea). Currently he is the first below the line. If he can repeat Oberhof he would be in. But anyway he will qualify via Cross country i guess. Still would be great for him to start in biathlon.
Luge: Obratov, she is probably out, i dont see an impovement there.
Bob: our team is not good enough.
Figure skating: Vrdoljak is without a chance in my opinion, unless all others have a very bad day and he has a great day, which will not happen. Petranovic/Sousa only with chances if Germany and France do not use their 2nd quota. If they do it is hopeless.
Snowboard: Jugovac currently in 36th place, 30 qualify. It is going to be very tough, probably not, unless some NOC do not use their quota in SS/BA. Stojak to far away, maybe 2022.
