Typically, motion controllers aren't very good at adapting to different gameplay situations -- not unless you're willing to slap on a cheap plastic shell, anyway. Sony may improve that state of affairs in the future, though, as it recently filed for a patent on a modular PlayStation Move controller. The concept lets gamers attach parts to the Move that change not just how it feels, but how it behaves in-game. A set of "limbs" would turn it into a humanoid, for example, while a rotating part could switch between a gun and a sword. It's an intriguing idea, although we wouldn't count on seeing it any time soon. A modular system would likely raise the price of a future Move controller, and Sony has lately focused more on the DualShock 4's Move-like features than dedicated peripherals.
