Didn’t see this coming. It appears that Korg has been working on a 6-operator FM synthesizer very much in the style of the Yamaha DX7.
Not much to go on at the moment other than the image and a thread on Reddit. You can see the mass of algorithms but more interesting are the knobs and sliders over on the left. It looks very dated, very old-school Korg digital synthesizer which is probably intentional.
More information when we get it….
