RIM always seems to have something new up their sleeves. The latest is what seems to be a patent for rotating keys on a physical keyboard. This could be an updated patent to the rotating keyboard patent that was seen in August 2010. The patent explains the ability to set custom keyboard designs for specific variations and scenarios.
The abstract of the patent:
A customizable keyboard for a handheld electronic device is provided. The keys of the keyboard are rotatable, either individually or in groups, either under manual control of a user of the device or by means of one or more micro-motors or solenoids controlled by a microprocessor running software on the device. The keyboard may be integrated in the device or may be detachable therefrom.
