Spirited away in the PC Gaming section of IGN is a rather well-written editorial of the past, present, and future of motion-sensing controllers. It examines how the PS3's and the Wii's new controllers might introduce a new visceral thrill into many tried-and-true genres, how it might attract new gamers, and so on. It's nothing terribly new, but it does have some interesting comments from the MIT professor/video game enthusiast Henry Jenkins, a revelation about how bouncing puppets might appear on the Wii, and a convenient collection of each company's stance on the future of input devices. Take a gander, if you're willing.
[It's so bad.]
