A world of dual analog inputs is coming to the Nintendo 3DS, set to debut next month at a trade show in Tokyo. According to the French technology website 01net, Nintendo has been developing a joystick for the 3DS and asked certain game developers to come up with new titles optimized for the dual-controller console. The site also claims that a 3DS replacement is set to debut in early 2012. The rumors sent Nintendo shares to the moon, rising over eight percent on the Osaka Securities Exchange.
