I have been thinking about this one quite a bit lately. I say no. Please follow my logic - Apple implemented the T1 in the MacBook Pro for Touch Bar and Touch ID only because it had a captive keyboard, meaning the keyboard plugged directly into the logic board, so there is nothing in-between that would be able to intercept the communication between the Touch ID sensor and the Secure Enclave in the T1. The question then becomes, how does Apple replicate that security over Bluetooth 4.2 and/or 5.0? I do not see Apple releasing a wired keyboard again ever, so a Touch Bar and Touch ID keyboard is going to need a bigger battery as well (others have pointed this out before me), but the security aspect is the one that I think about more. Also, when you are recharging the keyboard via the USB cable it disconnects Bluetooth, so you also have to make sure the USB connection is secure as well. Lots in play, I do not see it happening ever, but see the 13” MacBook getting Touch ID as a more likely scenario.
The flip side is that the keyboard in a MacBook Pro just presents as a USB device in System Information, so why would Touch ID NOT work over Bluetooth 5.0 and/or USB just as securely? Wish I had the expertise to answer the question authoritatively.

My hope would be that Apple gives us two “minis”, one in the existing case that uses Intel 28w U-Series CPUs and simply replaces the Thunderbolt 2 ports with Thunderbolt 3 ports at the same or very similar price points and a “Mac” that is like that mini on steroids, but uses the Core i5/i7 8xxxG CPUs with Radeon Pro WX Vega Graphics in a larger, more flexible chassis that allow for better thermals and up to 64GB of DRAM. This would also make a cheaper Developer box for AR/VR provided it also had an HDMI output.
Now, I will not be surprised when this does not happen nor will I be upset. Again, for most people, the gateway into the Apple world is the iPhone and/or the iPad and not a Mac. The iPad is the most logical choice for users who enter via the iPhone as then they do not have to purchase new applications. H/T to user
abizigal for that insight.
Unfortunately, I think the Mac Pro will be less accessible than most would like it to be and with a rarified price tag (5K base and up it goes).
However, I will try to be optimistic that Apple has not yet abandoned the Mac. Looking forward to Tuesday either way.
