Capcom has a new 3DS title on the way called Nazo Waku Yakata, or "謎惑館" in Japanese. (I got the Romanization from a trademark that came up when I did a Google search.)
Famitsu's first look this week reveals that you don't use your hands to play. Everything is controlled through voice, gyro controls and touch. The game will also apparently support 3D sound through your headphones or via your PC.
So what kind of game is Nazo Waku Yakata? No clue yet, but it does seem to be a pretty big title, as it has character designs from Tadahiro Uesugi and a scenario from Yukinori Kitajima. It's being directed by Minoru Nakai.
