The (2017) two-port MBP differed from the four-port MBP in four ways: (1) only two ports, (2) 15-W CPU, (3) function keys, and (4) lower price. The 2019 two-port MBP retains three of those four differences (all except the function keys). It thus makes more sense to call the 2019 two-port MBP being the two-port 2017 MBP with one thing, the TouchBar, added (and of course updated processors), than the four-port MBP with three things 'downgraded'.This is exactly what I am saying. Take a 13’’ touchbar MBP and stuff in a lower spec cpu, lower spec gpu, reduce 2 TB. Pronto.
No update to the old.
There’s no other difference with the other 13’’ touchbar MBP. It’s just a lower spec touchbar MBP.
Unless you also want to call the (four-port) 13" MBP as just being a lower spec 15" MBP (smaller screen, lower CPU class). Of course, your actual point, which you failed to articulate, is that the two-port MBP could always been seen as just a lower spec four-port MBP. Or even more to the point that using a 15-W CPU (and fewer ports) in the same chassis as the model with the 28-W CPU without making use of the smaller thermal envelope and less space needed for ports (eg, via smaller chassis) seems to be merely a price differentiation exercise.
