Gloves are a possibility, but pure gesture input just doesn't work (as repeatedly demonstrated with Wii, Kinect, and Leap Motion). Whatever they release, it needs to have at least a few buttons and probably an analog stick or two.
All those systems can't deal with self-occlusion of the fingers but gloves can deal with it. Also, the gloves can be out of sight of the user (hands behind the back)and still be effective.

That's just untrue. I'm not saying that, from a gameplay-oriented perspective, gestures are better/more adapted (which is definitely wrong to say at the moment anyway). But for a data visualization and/or 3d world manipulation use, gestures are really promising.
The devices themselves and their lack of general use don't prove anything: The Wii and Kinect don't track the fingers, and the Leap Motion is a lot more spatially restricted (which might bring incomfort after prolonged use, and is unpractical for wide movements). Besides, developping new ways of interacting reliably with gestures is not something you can do in an afternoon, so it might take time for pure gesture input to prove its worth.
But the gloves don't fully reflect the positions of each of the fingers. It only senses when the touch points on the glove are being contacted. I couldn't flip the bird at someone in VR, for example.
