While Apple "may" add more memory to their MBP specs, I can only wish they could add more USB-C ports AND spacing USB-C ports to farther away each other.
Having two on each side (plus optional USB hubs) seems to be plenty. USB-C isn't perfect, but being able to charge from either side is a quality of life improvement.
The spacing, location, and number of Thunderbolt 3 ports is likely predicated on limitations of the port controller. I doubt we’ll see a significant difference in this area.
