Probably they will only be eligible for one thanks to their position on the SB list - they are currently 19th with 4CC and Worlds still to come, but I expect they'd get a host pick at CoR as well to make it up to two.
I take everyone's point about the importance of just staying at home to practice, but it is frequently said that the hardest part of skating with a new partner is getting used to competing with them & learning how they respond in that situation. Marina herself has said that S/K look good in practice, but it hasn't translated to competition. That's why I think it would have been better for them to do Bavarian Open or Russian Cup final - not high stakes event, but another chance to deal with skating a competitive program together. All the practice ice in the world can't give you that experience, you have to live it to learn how to manage yourself & your partner in that environment. I don't want to always compare S/K to I/Z, but look at I/Z having had 5 events together; you can see how it has engendered trust in each other, and when they had a big lift problem like S/K did at NHK, no one panicked, they got it down safely, got back into the program and finished well. S/K need that experience. As it is, they will have spent at least 8 months since their last competition by the time the next season starts & the international judges last memory of them is of the mess at NHK. A reasonable senior B showing could have helped both their mental approach to competition & their reputation with the judges.
