USFS may beg C/B to go to guarantee keeping the third spot. Say they don't go but some of the other top teams do -- Z/K, CPom, and GreenP might not be able to pull it off.
And I'll say for US ice dance what I said about the US men this last Olympic cycle... if the teams we have after ChoBat can't earn the spots themselves then we don't need the spots. It may not be fair to the teams who are all very talented & should get a trip to Worlds in the future, but if that's the case, go out and beat the ones ahead of you & then help earn the 3rd spot back.
As it is, I think at least one of GilPoir and GuigFab will also skip Worlds, maybe both knowing that FBCiz have already said they'll be there. The only reason for either to go would be if they thought they had a shot at winning the title but with FBCiz there, that's not happening, so there's not much upside. This is especially true for GilPoir who have SOI Japan coming up in early April. Go home, do the media circuit and get some rest before you go out on tour.
If I'm right about those two plus, obviously, ChoBat, skipping Worlds, then I think we are looking at an IAM podium sweep. Sorry, ZingKol ubers, they're going to get pipped at the post with ReedAmvru being given a nice Worlds bronze as a retirement gift and FearGib should bounce back for Worlds silver. ZingKol will finish 4th, CarPon will finish 9th, and we'll preserve our three spots barely. LopBri will be 5th, SmaDie 6th again, LajLag 7th, TurkVers will move up to 8th provided Matthias doesn't biff his twizzles, but if he does then they'll wind up behind CarPon like they did here in Milano. DavSmo will wind up 10th.
Canada will lose their 3rd spot, Italy will lose their 2nd spot, France will gain a 3rd spot, USA will maintain 3 spots, and Spain, Great Britain, Georgia, Czechia & Finland will also maintain 2 spots (though Georgia may struggle to use their 2nd spot unless Kazakova/Kasinskji can improve next season enough to earn the CTES mins).
