According to Moonphase Diary, a new 「Fullmetal Alchemist」 series has been confirmed. As you may recall, this information was originally leaked out when a list of animators from Bones was made available over the net — however back then it was simply just seen as a rumor…

A formal announcement will be made on the obi strip included on the 20th volume of the manga — on sale 08/22. The new series is reported to be a remake that will follow closely to the original manga. Broadcast is rumored to begin in April of 2009.
