Originally I thought so as well, but my new theory is that none are missing, all have been revealed... we just got some things wrong.

Fire + Wind = Scorch Fire + Lightning = Explosion Fire + Earth = Lava Fire + Water = Boil Wind + Lightning = Magnet Wind + Earth = Crystal Wind + Water = Ice Lightning + Earth = Steel Lightning + Water = Storm Earth + Water = Wood

Just my 2 cents.
