With the way the Men's field has been shaking out, if I was the USFS, I'd be holding out on naming that SkAm TBD spot as long as possible. With the strong possibility that Kvitelashvili withdraws closer to the start of the GP, there's a decent chance Hiwatashi could secure a 2nd invitation and the TBD spot go to someone else (not sure who, but yeah...) As it is, I won't be at all surprised to see a Euro-based skater invited to MKJW - my money would be on Frangipani or Selevko - it won't be a Japanese guy since there are already 3 competing there. Also - Japan is now maxed out with 3 men at every event except SCI, so the chances of Miyake, Shimada or Honda getting an invitation are really slim.

And the Women's Alternates list - wondering if Ryabova is going to be able to compete at NHK seeing that she had visa issues for SCI. If so, the only options for the JSF will be Kiibus, Kitromilis, Paganini, Daleman & van Zundert since JPN, KOR & USA are maxed out with 3 women each already there, lol.

The USFS doesn't have a lot of options for the newly vacated SkAm spot - 5 of the teams on the Alternates List are either already at SkAm or Americans.

Seems pretty obvious it will be one of the Canadian teams or Harris/Chan that get the invitation. Though maybe they'll cut a deal with the FFSG to invite Lagouge/Caffa and, in return, the FRA TBD spot will be given to a US team (especially since that's one of the two GPs that doesn't already have 3 US teams).
