Olga Ermolina/Tatjana Flade's interview with Alexandr Zhulin for fsrussia.ru
[...]
The GP are not yet clear, but if all goes well we'd like to participate Moscow and China, but we'll see. Moscow - for the obvious reason, China - to understand what the scheduled will be like at the Olympics - the competition will be very early and the practices as early as 5am. Hence in Krasnoyarsk camp before the Olympics that our federation kindly organizes we'll wake up very early and have run through at 9am. We have to get used to it and not just got up, went and lost the Olympics, I don't remember a thing.
So I think that provides a lot of additional clarity for the Grand Prix events (assuming they happen in the normal fashion). So one might guess:
America: Hubbell & Donohue, Stepanova & Bukin
Canada: Gilles & Poirier, Chock & Bates
China: Sinitsina & Katsalapov, Stepanova & Bukin
Japan: Hubbell & Donohue, Guignard & Fabbri, [Papadakis & Cizeron]
France: Gilles & Poirier, Guignard & Fabbri, [Papadakis & Cizeron]
Russia: Sinitsina & Katsalapov, Chock & Bates
Not ideal return conditions for Papadakis & Cizeron, but they're kind of stuck based on which federations are likely to be interested in inviting them, so they kind of have to do it this way unless they decide to start the season taking on Sinitsina & Katsalapov in China (which would be an aggressive, interesting movie, to be sure), in which case Guignard & Fabbri would also go to China instead of Japan.
I'm also not entirely sold on both top Russian teams at the same event, but it's impossible, based on the way the top seeds are configured (and where P/C will presumably go) to avoid that unless Stepanova & Bukin are willing to risk being the bronze medalists at one of their events, which I would think both RusFed and the dancers themselves would also want to avoid.
Actually, now that I think about it, it's also possible that Chock & Bates could choose to do both North American events back to back (as Hubbell & Donohue did a couple of times), if they're angling to try to claw their way back over Hubbell & Donohue on the domestic side. Which would tighten Stepanova & Bukin's options even further.
