perhaps, but that strikes me as not very elegant… we can be fairly certain at this point there are only 5 1/4" jacks, 4 USB host ports and 1 USB device port. also, the mention of radio OSC and the fact that a bluetooth(?) adapter was shown in one of the pictures seems to imply that’s how it communicates (since it can also do MIDI but there is neither DIN nor minijack MIDI). so maybe there is something that converts OSC to CV - an additional module? something that can be plugged into a USB port on ansible or teletype?
the truth is likely both more simple and more complex as is usually the case…
since it supports grid adding arc support would be trivial. and the cool thing about norns is that you could probably have both grid and arc connected at the same time. and faderbank!
