I just discovered this:
Music Tribe has applied for the trademark POLYTOUCH in February of this year. Medeli has the same trademark, from May of 2020. The Medeli Keybed PolyTouch is used by their subsidiary ASM in their Poly-Aftertouch Hydrasynth Keyboard.

It would be a very strong move if Behringer really does develop their own Poly-Aftertouch Keybed.
