TemptingToys.net sent us an update. Henkei Black Skyfire available for pre order for $74.95 plus s/h: Visit TemptingToys.net for all your Japanese, Rare and Vintage Transformers needs!
I think they're the same as Henkei Skyfire's missiles. Is there an actual release date for this guy or is it still just "March 2010"?
To answer my own question: Automaton Toys here in Canada is scheduled to have them in stock next week, so the release date in Japan should be either this week or next week some time.
