that's right but the 'regular' one had 4. I've already seen a pro user (in music production) complain about this.
But my point here is that the fact they are both the same supports the theory that the logic board is the same on both models.
They’re continuing to sell the 4 port Intel 13” Pro.
Maybe they'd launch a more expensive 4 USB-C/Thunderbolt ports model with their more powerful chip (and upto 64/128GB memory) like they did with the earlier MBP13s.
