I can tell you a bit about the cut write-ups, but keep in mind that this is all subject to change come What Fire Has Wrought.
Water Dragon style makes use of razor claws. Its techniques tend to emulate the fluidity and formlessness of water, and manipulate the water within the human body (and its divine analogue, Essence, in gods and other spirits) to a debilitating or deadly effect.
Wood Dragon is a staff style. It's the most esoteric of the Immaculate styles, perceiving and manipulating the Essence of both life and death. It's one of the only styles that can be used for healing, and has a capstone signature move that destroys an enemy's soul with a single strike.

It was a change we made for the Immaculate write-ups in the core. The actual style may end up going another way, but it so far it hasn't to my knowledge.
