I mean, we might see it considering how FGO's output has slowed compare to their earlier years. It's in decline but still take time to actually EOS(End of Story).
Still, if they were to make a 3D sequel(excluding the half-ass Arcade game), they would need to focus on 3D modelling more than art so less characters output and maybe, just maybe, Raita is free and can finally resume making doujins!
