A touch bar on the computer itself seems unlikely, but a touch bar on the keyboard is definitely possible.
Touch bar on the computer would be at least as likely as a keyboard... probably more likely.
1. Apple has dumped wired keyboards. Highly doubtful they are going to bring back wired keyboards for a touch bar. Wireless keyboards the problem is bandwidth and battery life. One have to feed a constant steam of data to the T-series chip. Two you have to feed a constant stream of power to the T-series. "But it is a iPhone chip" isn't going to get you out of that hole. Run constant screen active time on a iPhone and watch the battery level shrink. Probably not going to get anyting like the normal lifetime for a battery bluetooth keyboard at all.
2. The T-series has some system management features. With Apple buying up some of the Dialog PMIC IP to merge into future custom system and power management chips that is probably only going to go up over time. It is going to be pretty difficult to be the "system manager' chip when off in the keyboard ... that can be detached if the Bluetooth connection doesn't work. the system manager is what helps set up the bluetooth and all of the other high level I/O features.
T-series also does sound and speakers so that too is highly odd ball for a keyboard. Secure enclave in a easy to walk away keyboard ... again more of a head scratcher than a "good idea".
3. Not as function key augments/substitutes but replacing the physical buttons and status indicators on a system. Those could be system status ( like what folks put into activity monitor or istat menus. ) or some sort of Siri interface. Remember Apple has taken away start up chimes too.
Also could somewhat help if wireless keyboard goes belly up and need to a controlled shutdown or start another basic pairing. There would always be one physically attached input system ( even if limited to a couple of 'buttons' ).
As a function key substitute the touch bar only makes sense in the context of laptops. For desktops and larger screen sizes, the screen is highly likely to be placed farther away from the keyboard. Grow that screen and bar gap too large and it makes less and less sense.
All that though ... Touch ID would make more sense than also putting on a touch bar. More likely the Touch Bar would probably mostly just mean "costs more" as the biggest impact. ( same with a discrete keyboard. ). It mainly just looks good in whipped up, show off designs. There isn't tons of inspirational design insight there.

Couldn’t disagree more. It’s only by not buying the 2013 Pro (if it doesn’t suit you) that users can send a message that Apple needs to offer something different. If that means leaving the Mac platform, so be it. Users have to do what makes sense, given their requirements. They can’t buy a computer Apple doesn’t make. ...
While users can take that approach, the issue is going to be that is far more likely to get slower response times from Apple, not faster ones. The fewer people that buy the closer it gets to what Jobs called "nobody is buying" and then it gets put on the 'axe it' watch.
Apple isn't out to make everything for everybody. So if Mac product A,B,C grow and D and E shrink then more than likely A, B, and C are going to be first in line to be assigned development resources. if D and E happened to be 50% of sales then perhaps would get a different ordering, but if already relatively small (so on 'watch list') and protest just makes it even smaller... that action may not lead to a correction at all long term. For non strategic products that is a tactic with risk.
The core issue is what are actually seriously hard functional requirements and what is "I'm using to buying something that looks like this form so want another form just like that" that are in the 'like to have' area. There is also battles over control which isn't really a functional requirement either. For folks who have gross distain for any Apple design choices then that is more a disconnect than a requirement. Apple is newegg or Fry's. They aren't just selling barebones boxes. Never really were even before the Mac came along; and Mac moved past that.
Folks who have objective, real requirements mismatches. Sure get something that works. Apple doesn't "hate your profession" they just don't have what you want. But the notion going to "back seat drive" Apple strategic policy with a relatively small (to mac sales/revenues ) collection of Mac Pro non purchases .... that has problems in the real world. Apple isn't broke and desperate.
