I feel like the God Knights will retreat with the children for the time being and will attack at a later time, during which all the straw hats will have to learn haki.
My theory is that Rayleigh will bring Hancock to Luffy in Elbaf and will reunite with Gaban and both will teach the straw hats haki(minus the trio and Jinbei of course).
Brook and Robin will defined fight Gunko and Sommers at the end of the arc but this time they have haki so they can 1 vs 1 the God Knights and I believe Brook eventually defeats Gunko and frees her from Imu’s control which will kill her and after an emotional final goodbye between them, the actual Imu will finally come for real and will face Luffy at the climax of the arc, setting the stage for when they fight again in Laugh Tale to settle this long war once and for all.
