I don't know how much further ICE efficiency will improve, but to improve city ratings the weight will have to go down and to improve highway ratings the frontal area and/or Cd will have to go down.
Pickups, SUVs, and even cars currently have needlessly huge frontal areas, all due to fashion. When the high mpg requirements kick in, someone will have to convince the buying public that long and low is better than high and boxy. It's not impossible- the 50's and 60's were all about long and low. What goes around, comes around.
