One more Thunderbolt Port, HDMI 2.1 port that allows HDMI out AND in. Camera improvements, and just overall subtle improvements in cooling for the increased CPU/GPU/RAM improvements. These laptops are nearly perfect to be honest. Maybe in a few years make the trackpad able to mirror a portion of the regular display so we can use Apple Pencil to draw. Maybe have 10key in a larger 18” model or figure out a nice way to implement it into the new palm rest or trackpad also like others, but I’m still on the fence on that one. Only if they can implement it in a really good way.
