I doubt that would happen if there were a row of physical half-height function keys between the numbers and the touchbar. But I also doubt they would make that laptop, it would require a smaller touchpad and most people wouldn't want that, myself included.

Or 4:3 screen, but we can keep dreaming there...

My hope is that they offer the touchbar as a configurable option on all MacBooks going forward, at least until they realize no one is buying the ones with the touchbar included. Maybe some video editors like it? It's a failed experiment from where I'm sitting.
