Mishin and Moskvina have ended their decades of cooperation it seems. Moskvina has opened her own school which will be at a new rink, which was reported on rsport in March (but somehow was largely unnoticed, I guess because of the major championships held in March). For many decades Mishin and Moskvina worked at the same rink, Yubileyny and in December 2014 they opened a school together called "Star Ice", which operated at two separate rinks, Yubileyny and the other one (but Mishin and Moskvina's elite students stayed at Yubileyny). Now Moskvina has split from "Star Ice", taking with her not only all her Pair skaters and coaches but also some Singles skaters and coaches. Moskvina's new school will have both Pairs and Singles skaters. Among the Singles skaters at her new school will be Nugumanova, Gumennik and Kutovoy. Their primary coach will be Veronika Dayneko, who worked in Star Ice as Kutovoy's coach.
According to Tatjana Flade (over at FSU), Mishin told her in Tartu that Nugumanova and Gumennik have discipline problems and that their parents are stage parents. And that's why he punished them by not bringing them to his summer camp in Tartu. Whether this is really true or not (the behaviour of the kids and their parents), who knows. And why Mishin chose to tell a well-known FS journalist such negative things about students who supposedly had not left his school yet at that point, I also don't know.
But the split up of "Star Ice" is indeed a reality. Further details I am not really clear on, if I find it, I will post it.
Edit:
The rumour is that Urmanov is returning to SPB to work in Moskvina's school.
