I'd love it if they simply re-issued the 2013 model. I have a 2013 MacBook Pro and it has been great. Every iteration since then has been worse (keyboards, batteries, touchbar, etc).
Logic Pro is the only thing that might force me to by an inferior current model Macbook if my 2013 model croaks. I'm about to start experimenting with Ardour to see if my Logic Pro dependency can be removed.
What about if they have a touch bar but also have a hardware escape key? That's really the only thing about the touch bar Mac keyboard layout that I hate. (I don't actually mind the feel of the butterfly keys -- I'm typing on them now -- but I don't love them, either. Although if they kept this key feel, maybe just doubled the travel, and brought the reliability back in line with the older scissor switches, I'd be totally on board.)
