Futuristic controller from Yamaha

Things like this were mentioned as instruments of the XXI. century a couple of years ago - and really! Yamaha considers their newest baby, Tenori-On as a game thus they distribute it only within the UK but nobody knows what can be the future of this device. What we can see is we can get - a 16 by 16 push button matrix with LED inside, but the actual spec will be revealed only in 4th September at the launch parties and on its website which is still half-empty nowadays.
