It would be nice to see Denis Ten make a successful reappearance at Worlds, but I think he needs time to rest. He wasn't ready for the Olympics.
Denis Ten retired right away after the Olympics. Abzal Rakimgaliev has the TES to represent KZ though.
As a fan of Kolyada, surely you agree that Kolyada needs help choosing more suitable music and making smarter technical decisions. His team pushed him too hard too soon -- he was adding too many quads all at once and it didn't serve him well. With the PCS marks he was getting, if he had just done 1 quad in the SP and 1 in the LP I suspect he would have skated better and received better marks. However, his mental game appears to be suffering as well, so perhaps lowering the difficulty wouldn't help much at this point. I don't know for sure.
It is a shame he had such a bad season, and unfortunately it wasn't limited to just "one bad outing." Nearly all his performances this season have been riddled with large errors, falls, pops, giving up on the performance... My point was that he needs to make some major changes if he wants to get the most out of his talent. He clearly has a lot of potential and can perform really well when given the right vehicle. Sadly, this season he was given horrible programs that were too difficult and did not suit his personality or his performance style. I'll still watch him if he performs that doomed Elvis LP at Worlds, and I'll still hope for him to skate cleanly, but I am not optimistic.
Both Hanyu and Ten (Japan and Kaz) are on the start list! Everybody says that at least Yuzuru is not participating. But why ISU posted this list?
The ISU publishes the entries that the federations give them. It's not uncommon for feds to enter a skater initially then replace them later if they decide not to go due to injury, etc. So this doesn't really tell us if Hanyu is going or not.
Thank you so much for the answer. Then I keep hoping I/M to skate for this WC
Denis Ten later announced that he didn't decide anything, the retirement announcement was a wrong translation from a journalist. He's now on the official list for Worlds, with Rakimgaliev as alternate.
