Interesting. Can't find any information on price. And that video -- even when slowed it down to 50% speed, the text was still racing by faster than I could read it. The 4.3" screen seems kind of small by today's standards, but maybe that's all it needs. Except for the pads on the right, it almost looks like a Genos. And, of course, when I see that ribbon controller, I automatically think "Yamaha CS-80", and this controller looks much more advanced than that.
We'll see what Yamaha does. Quite a few of their models are now getting a bit old and are due for an update.
