So I ran a few different scenarios and I think a lot may come down to the men event (who is skating, and how they skate). Pairs and Dance seem pretty set to me.
I think the qualifiers for the free will be in order: CAN, RUS, then JPN/US in either order, and the last spot will be between CHN/ITA. Depending on which men the US uses, how well M/R skate in the dance event, and which one between CHN and ITA qualifies, JPN really may challenge the US for bronze.
I think we will see some surprises in terms of selection for the teams, as not all countries may care about the team event (especially the ones not in the running for medals).
