Engadget just put up an article with pictures and a video showcasing Sony's version of motion control. From using them, they seem light, have a main and sub-controller, and shiny glowing orbs on the top that seem to change color. It's still in development, and it shows when they are playing a demo. The demo, according to Engadget, wasn't as precise as Wiimotes, and the refresh rate was slower as well. These controllers are scheduled to be released this fall.
