(CNN)  -- Four years ago, Nintendo's gesture-tracking Wii system proved the power of motion controls to extend the mainstream appeal of video games. Now Microsoft and Sony are readying their own motion-sensing solutions. But will these user interfaces be novel enough to move gaming fans en masse? Launching September 17, ($99.99 starter bundle) the wand-like PlayStation Move claims to offer greater precision than the Wii remote when translating gamers' physical movements into on-screen actions. Debuting November 4, Microsoft's Kinect system ($149.99 starter bundle), employs a 3-D camera that makes your body the controller and eliminates the need for handheld hardware.
