It's not concluded yet.
It's weird. As a swiss, one should hope for a bad tournament. His hattrick in the pre-tournament makes me feel a bit inconvenient.
To lose a prospect of his caliber would be extremly painful for Swiss Hockey.
But it's not an easy decision to make for Rochette. There are pros/cons for either side.
He's probably good enough to play for Team Canada's U18 and U20 with his peers. With excellent chances to medal. But will he be good enough to ever compete for a spot on the Senior team with its deep pool of talent? It's certainly a risk.
For Switzerland he could play a big role in the junior teams even as an underager. But has close to no chances to medal. With a proper development he's got all the chances in the world to be relevant for the senior team as well, thus an outlook on going to the Olympics in the future, and playing some WHCs for a team, that has shown recently to be very competitive when things working well.
He stated in the summer that he tends to play for the nation he mostly grew up in. But he sad that in Switzerland to a swiss journalist, so...
Short-term, I guess, it forces the Swiss Federation to answer the strong luring of Hockey Canada by pretty much making Rochette a lock for the U20 WC... as a triple-underager. Otherwise he would have only a small chance to make the team.
Anyway, if he ever plays an offical ranking tournament for either side, he'll be locked out of a nation swap for 4 years
