Mario's upcoming 3DS title will feature motion controls, but no StreetPass goodies.
"Unless a spectacular idea comes to mind", Super Mario 3D will not feature any StreetPass content, Shigeru Miyamoto stated in a recent interview with The Telegraph. However, the game will make use of the 3DS built-in gyro sensor, instead of a second analog stick.
Miyamoto states that "having the gyro sensor, you can replace the analogue stick by moving the console, which is very intuitive." One can assume this means the use of camera movement will be handled in much the same way as Face Raiders and the upcoming Ocarina of Time 3D, though exact details on the motion-based movement were not elaborated upon.
The game will be shown in much more detail come E3.
