I have no inside information here, but I suspect that Apple sees the MacBook Pro as the Mac aimed at developers, not the Mac Pro. MBPs are more common in Silicon Valley than roadside poppies. So while the Mac Pro was the first stop on their Hardware Apology Tour,† the 16" MBP is the "please stay with us, developers" machine: fixing the keyboard, increasing the performance substantially, and not raising the price. †Not that they'll actually ever say "I'm sorry" out loud, but it's pretty clear they're rolling back some of the late stage Ive-isms. Yes, I know they kept the Touch Bar and didn't add ports, but I think they're all fully committed to USB-C as the Way Of The Future™ and, uh, somebody high up loves that damn Touch Bar.
