What we really need is a 21st century editor construction kit with Minority Report gestures, eye tracking, and voice input, as well as the keyboard.
And for vim (inspired by [2]): [3]
I'm sure gesture tracking would probably not be too hard, using any of a number of VR input devices now on the market. Eye tracking would be harder, as I'm not aware of any consumer-level eye-tracking technologies out there. You could certainly have head-tracking pretty easily, though.
Now integrating this in a way that would actually be fluid, natural, and useful is another story, though. Also, I'm personally not sure how many big body movements I want to be doing while using my computer (unless I'm trying to exercise, play a game, draw, conduct music, or lose weight).
Ideally, I'd want to be as motionless as possible while being as comfortable as possible and while having maximum flexibility and efficiency of input. Keyboards are pretty good for that.

VoiceCode is a $300 product. http://voicecode.io
Is it worth the money?
- Gestures might not make sense in many locations (tiny cubes with limited space, for instance), or prove problematic for Deaf individuals (learning, effectively, another signed language). That said, I totally want to select text, make a yanking motion with my hands, and have it get put onto the clipboard. - Eye tracking would be an immediate no-go in any sort of closed facility - Voice input is also a no-go in closed areas, and would be extremely annoying in cube farms - far more distracting than they already are.
