Every big Apple innovation on the MacBook Pro line has been preceded or followed with a standalone version. -The unibody keyboard - Followed up by similarly designed USB Apple Keyboards less than a year later -The unibody trackpad - Followed up by the Magic Trackpad 18 months later -The 2016+ MBP trackpad - Was preceded by the Magic Trackpad 2 in 2015 -Retina displays - Preceded by the Thunderbolt Display in 2011. History would suggest that we should have standalone touchbars and butterfly USB keyboards by now. Yet we don't. To me this tells me 2 things: 1. Apple sees the touchbar & butterfly keyboards as failures 2. Apple likely will not continue with the touchbar & butterfly keyboard in future versions.
