Um, no.
In summary . . .
We have one FSU poster who has stated that A&S have split. (No link, written evidence, or secondary poster to confirm this or support the statement as of yet).
We do know A&S were listed on the sub list for the first JGP and then were removed. And we do know that a week before that she had stated that she was competing in a later JGP.
And we have a
rumor of a
tryout with Drozd.
That's what we've seen on FSU thus far. Which means 1. It's possible it's just a rumor, and there was no tryout, 2. It's possible she is skating with Shchepetov but did go have a tryout with Drozd. 3. It is possible that she had a tryout with Drozd that did not work out. 4. It is possible that she is currently trying out with Drozd and nothing has been decided.
It does sound like Drozd is now with Zhulin, which is interesting in itself, IMO.
