Bobrova has tweeted her support to the Russian dancers:
Екатерина Боброва @crazybober
Rough translation: Good job, kids!! [Congratulations on] your first day! Keep going!!!
As for Shpilband, another team of his is Kriengkrairut/Giuletti-Schmitt -- who announced after U.S. Nationals that they were joining him.
Another new team with Shpilband: Yura Min/Timothy Koleto, who plan to compete for Korea.
By the way, I learned from the link above that Greg Zuerlein is a member of the Shpilband coaching team. So former partners Zuerlein and Chock now are working together as coach and student, I guess??
