I found it...
http://dai.ly/x601v5eMy assesment
10" touchscreen
6 rotary encoders
9 sliders (hope they both have the lights of the Montage
And indeed some buttoms direct under the screen... could be panel memmories
A dark video, its probably hinting that the Genos will be black, probably the same color and metal housing of the Montahe
All in all, i would guess, the size to be somewhat smaller then the Tyros5..
Hard to teel, time will tell more
