Dualo use will take off
The new Dualo keyboards (based on the sonome key layout, like the Axis), are soon to enter production.
This will present players the prize of a  combination of portability, fast learning, ability to play in any key, and a solid coolness factor. I expect this to be the "IT" instrument of 2015/2016.
In a single generation the Dualo could go from "odd" (right now) "cool" (3 years) to standard. Lets see if it happens.

Terpstra Keyboard
For the 280-key Terpstra Keyboard, to come out this spring or summer, the possibilities are great: there is so, so much that can be done by viewing music as, not a line of discrete, invariable pitches going up from left to right, but instead as a moving sheet of sound.  The advantage will be a solid surface (excuse the pun) to innovate upon.
