...and how would you connect it? No KPA has Bluetooth or a WiFi chip.
I think the notion of a mobile app with the current hardware is complete fantasy.
Phone paired via bluetooth or on the same network (doesn't have to be wifi, i have a mixed wired/wireless network where all devices talk to each other no probs). The new editor talks to the KPA over USB as well as to all attached/paired/reachable devices so i don't see what would be so complicated about remote controlling via app when the editor is running, or could be just a headless daemon as a bridge.
For talking directly from phone to kemper sure would be more difficult but judging from this thread it seems the editor will be such a vital element that most will be running it 24/7 anyways
