I agree wholeheartedly!
It just seems ridiculous, there must be a reason.
Someone over on the Nord forum claims they spoke with Nord and it's confirmed as being canned, but this was a couple/few months after the module was removed from the official Nord site.
Looks like the ND2 is the high water mark for the series, real shame.
Obviously it would never happen but Nord could easily have developed a tabletop groovebox based on the ND architecture/engine.
You would only need leds on those buttons and it would be a step sequencer, you can imagine the rest!
