Although the comments seem against it, I'm for it - I've played piano (and organ) for some 45 years now. You have to remember that the piano is mainly a percussion instrument, and there are few options to temper the sound, outside of sustain and such. Synthesizers have had the same capability as shown in the video, but you had to reach to the side and twirl a wheel to get the same effect, which detracts from the playability. Initially, this is not suited for traditional classical (probably better for jazz) but who's to say someone couldn't write a new classical based on this instrument (although goodness knows what the musical notation would be).
