Right now, it's been confirmed that the Arcanist will have 2 different Carbuncles (Emerald and Topaz), the Scholar will have 2 different Fairies (healing and buffing/dps) and the Summoner will have 3 different Egi's (Ifrit, Titan and Garuda).

Will we be seeing more types of Carbuncles and Fairies to fit additional/specific roles, but also more Egi's like Ramuh and Leviathan through content updates?
