This week's issue of Famitsu magazine contains the first word on Drag-On Dragoon 3, latest in a cult action-RPG series that came out under the name Drakengard in the U.S.

Not much is known as of yet about the PS3-exclusive game, other than it stars a pair of sisters named Zero and One and a mysterious "Singer" whose lethal songs are further strengthened by the blood of its foes.

The first two Drakengard games, both PS2 exclusives, were a mix of ground-based hack-n-slash action and dragon-based combat. They were known for their dark story settings, extensive gameplay depth for completion freaks, and mind-bending endings that fans are still talking about today.

Exactly who is developing Drag-On Dragoon 3 is as yet unknown. The first two titles were created by Tokyo-based developer Cavia, who went on to make Nier for Square Enix in 2010 (a title that may as well have been Drakengard 3 in terms of gameplay and dark, brooding setting) before getting subsumed into AQ Interactive later in the year.

More info as it comes.

Update: Further sources have confirmed that the sequel is being developed by Access Games. A number of old Drakengard and Nier staffers are involved, including producer Takamasa Shiba, director/writer Taro Yokoo, character designer Kimihiko Fujisaka and music composer Keiichi Okabe. A release is planned for Japan within 2013.
