Crossbow - Maybe we'll have hunter?

Hammer - That's my bet for new Tank's weapon.

Gun and Sword - Gunblade? Again?

Flail - Mace-class weapo would be interesting

Bomb - I doubt. But I'll be forced to cosplay Klee if that's a thing.

Yo-Yo and Whip - I can't see that. Specially whip, that at previous final fantasy games was always a dancer weapon.
