Otogi 2 Immortal Warriors - 2004 VG was released on:

USA: 19 October 2004 (North American release)

The producer of Otogi said that "Metal Wolf Chaos was a good break" before he went back into Otogi. This was after the release of Otogi 2, so I think there might be hope for Otogi 3. But remember, Otogi series wasn't very successful, investing more money into it might not be a good business decision for Sega (or anyone else for that matter).
