The picture, which was reportedly taken from a Kinect 2 dev kit, was posted by French website Xboxygen.
The image suggests that the new Kinect will be able to make out clothing shapes, and accurately track individual fingers.
Earlier this year, a leaked document claimed that the Xbox 720 will feature Kinect 2, 3D technology and the long-rumoured Xbox TV.
Kinect 2.0 is said to feature improved tracking, dedicated processing, and with better play space and high definition.
Previous reports have suggested that the updated Kinect device would be accurate to the point of being able to read lips.
The next Xbox is expected to launch within the next 18 months, supporting both Skype and the Windows 8 operating system.
