I'm pretty sure it's 10 teams like last time. Czechs in my opinion are sure to qualify.
(currently ranked 1-6) will definitely be there.
(7) doesn't have an Olympic-caliber ice dancing team, and Zandron will have a very tough time qualifying for the men's event anyway
(8) to my knowledge doesn't have any active pairs teams (none have appeared at their Nationals since 2018)
(9) will almost certainly qualify either a woman or a pairs team at Nebelhorn, so they should make it
(10) has no men, pairs or ice dancers
(11) it would be a miracle if either Hallam or Jones/Boyadji qualified, given how few spots are in play for men/pairs
(12) have already qualified in 3 events, so they will be there
(13) have a strong pairs team and ice dancing team, at least one should definitely qualify at Nebelhorn
(14) Czechs as it stands are #10, the last qualifiers, and will only need at most one additional quota for ice dancing
(15-20) are all missing Olympic-level athletes in at least one discipline, so even if they overtake Czechs on ranking points, they shouldn't be a threat
