I don't think he'll go for a 4Lo? I don't think this has been a jump he has focused on lately, since he needed to prepare for Worlds and select the most consistent jumps to work on.
And now that he's peaked, he's not gonna rush back to work on it again for an event such as WTT with such a short preparation time at that (assuming he took it easy for a few days up to a week after Worlds)?
I'm more curious to see what his and Yuzu's general strategies are going to be.
It's a fun fluff event, where they might wanna relax and not put too much pressure on themselves, and focus more on enjoying presenting their programs with an easier layout?
But then both might feel like they can't take it too easy, since they're also competing for their team mates and they have quite a rival in each other, so they can't 'slack' too much.
Yuzuru might also be looking for a kind of redemption skate or a redo, now that he's feeling fit (although that could mean just a clean skate for his fans, not necessarily beating Nathan)?
And in the case of Nathan, if you take a risk and travel in such times like these, you would wanna make sure to get the most out of it, also in terms of prize money, no?
I think both can be enjoyable, since the rivalry can be exciting but also a smooth skate in a relaxed environement is so nice to watch. But I do hope both decide on the same approach, since it would feel weird if one of them lays it all down, when the other one doesn't do the same.
ETA: If both of them water down their content, but someone like Misha and/or Shoma keep their Worlds layouts, they could also swoop in though.
