I would expect S/K to do CoC along with CoR, with H/D and G/P splitting IdF and NHK for their second event. My guess is C/B will also choose CoC (they've done it several times before and isn't it being held in the Oly arena?) and for the 2nd, they'd probably want a GP that P/C won't be at. The best case scenario would be to compete against G/P, who they might be able to beat, but the only opportunity might be at SC, and G/P will have the advantage of being at their home event. And even a 2nd place would get them to the GPF.
