Julia and Gracie and Marin Honda.
I don't think Sotnikova will dominate. She'll win some titles, but Gracie Gold and Julia will catch up to or surpass her. If Kanako stays she'll be a contender, but I heard she was retiring. Others to watch - Radionova, Satoko Miyahara, Polina Edmunds, Zijun Li. I'm not sure about the Canadian ladies. I think Daleman may eventually overtake Osmond.
Meaningless . It depends on where it is held not on who is capable .Or on who the judges are.
In Russia no lady can expect consistent "pushes" from the federations. There will be always ups and downs. Quite impressive to see the change in just one SP. If Sotnikova does poorly at worlds, she can lose her position easily. In this sense, Gold is more advantageous because no other US ladies would challenge her in near future.
