Barring disaster, I expect Wang/Liu to bump S/F from SB 24. They are CHN #1, and they have politik none of the other do. (Although I haven't looked at the judges list, 8+ points in ID is a huge gap.)
However, this season, W&L mucked up their twizzles in the RD at 4CCs. Their potential score is higher than what they had there. And for that reason, plus the fact that they have--upon occasion--defeated some of the teams currently on the SB list, they might get there. An invite to World Team Trophy, though, that's a real advantage for them.
Turkkila & Versluis also left points on the table during their free skate at Europeans.
(He missed the twizzles both there & at Universiade if I remember correctly). And Reed & Ambrulevicius bombed their rotational lift at the end of their FD at Euros and may have left even more points on the table. (I wasn't factoring them in, but it's not impossible). There were some really high levels at Europeans. (Level 4 step sequences for teams that have never had one in their lives). Don't know if Worlds will match up to Euros/4CCs or not.
And finally, there is Nazarova & Nikitin, who have been absolutely on Team Trainwreck most of the season; but they did look better at the Ice Mall Cup, and they have brought in the scores before. They also defeated Evdokimova & Bazin in both portions of competition at the Ice Mall Cup, though E&B gave up their own points in the free there. So while I am A. a fan of N&N and B. not optimistic, it is not beyond the realm of possibility that they may be back on track for Worlds. They were only a point behind Soucisse & Firus at Worlds last year and above all the teams I've listed previously.
It doesn't matter if someone passes Ushakova & Nekrasov as, per Ka3sha, they are continuing in juniors next season.
