Square Enix still hasn’t said anything about Mini Ninjas: Hiro’s Adventure, but the game is in the works. On top of a trademark and domain name, we have a rating for the game care of Australia’s Classifications Board.
Hitman maker and the original developer of Mini Ninjas, IO Interactive, is making Mini Ninjas: Hiro’s Adventure. Hiro is one of the playable characters in Mini Ninjas and the youngest of the group. Look for the game at E3, maybe?
