The thing is with the whole Russian ladies have a hard time with success I could also ask this question
What happened to from the USA: Lisa Ervin, Jessica Mills, Sydney Vogel, Jennifer Kirk, Deanna Stellato, Anne Patrice McDononough, Katy Taylor, Emily Hughes, Christine Zukowski. Honorable mention can go to Bebe.
For Japan: Jungo Yaginuma, Yukiko Kashihira, Kumiko Koiwai, Yukina Ota.
And in some of the Russians case, a couple of them didn't exactly win as 14 year olds. So I think there were other factors to their disapperance. Plus the late 90s were a time when the Russians had a strong Senior team and so it was difficult to even make the teams then for Russia...One Russian girl of the names I mentioned one at 16. And was 11 at Juniors the next year. So I suspect she may have been a "skate of her life case."
If we ask what happened to Soldatova we have to ask what happened to Meissner, because Julia did medal at Senior worlds. According to wikopedia http://en.wikipedia.org/wiki/Julia_Soldatova She placed 4th at Russian Nationals in 2000, didn't make the world team and so she switched over to compete for Belarus. She came back briefly in 2004 for Russia. Her results did go downhill when she finally started competiting for Belarus. It seemed like some of the Russians switched to other countries. I think this could easily happen again too.Soldatova
