Hmmm I don’t think 3 Japanese and 2 Belgian are a foregone conclusion at all.
The only sure bets are Kaori and Leona in the top 5.
As much as I love Mone and Hana, they've shown some inconsistencies over the season that Chaeyeon, Isabeau and even Amber could capitalize on (although Amber is a STRETCH).
And Nina - well the judges and tech panels love her and her cheated jumps - so maybe they'll force her way into the top 5 but frankly I'd rather see Anastasia and even Maddie Schizas ahead of her.
