I agree with what you said Godisme, that what we're seeing is somehow the culmination of his Shinigami powers and Fullbring. Because none of the other Fullbringers even hinted at being capable of the type of "Bankai" he summoned. However, I stand by the belief that what he summoned isn't a true Bankai since a Bankai doesn't change the form of the user. At most they get a slight wardrobe change but that's about it.
