Sony's been on a patenting driving recently and has secured a crazy amount of add-ons for its upcoming motion controller.
Obviously they wanted to cover any and everything you could think of placing on a stick, if your thought of it, the hardware giant most likely patented it.
Kotaku's got them in abundance. According to the description, the patent is for an "Expandable Controller Device Via Hardware Attachment".
You'll be swinging Sony's wand Nintendo Wii style sometime spring of next year. Never thought I'd have seen the day.
