The predictions based on personalities about who switches where in the next updates are logical, but in that case the BB-s are pretty much fucked as a faction if the MC is sides with Sonja or Yrsa. The warrior clan based on strength would have their leader as the tool Ivar, Candrid behind him who's only forte is manipulation, Mathilda who's a great archer but also an idiot, and Katja who's good at fighting but again, dumb as a rock.
Meanwhile, the Ravens get Astrid who's at least knowledgeable, the girl with the supernatural ability, and Yrsa who's at least as decent in a fight as Katja.
Meanwhile the WW will have Astrja, good fighter, intelligent and now has ice powers, Sonja who has both brawls and brains, and Lizgard who's mid tier but also has another supernatural ability.
Although I can see Astrid leaving the wolves after Torstein dies and with her having an inferior complex to her sister, also Mathilda to clash with Astrja, but I don't see Lizgard and Katja being alienated enough from Nox unless she really goes to the deep end with something.
