Yeah so Ninja Gaiden: Dragon Sword has surfaced finally. Awhile back Team Ninja mentioned something about a DS project so I guess this is it.
From the scan it looks like you hold the DS like a book(Brain Training, Hotel Dusk, etc) and there seems to be game action on the stylus side and a map on the other side. Should be interesting to see how Team Ninja makes the game work with touchscreen controls.
