I suspect the heat pump will be hard to find outside of cold areas. Including it as a mandatory option will cost sales in the warmer latitudes.
I'm glad "Cold Weather Package 2.0" is an option on both EX and EX Premium US trims. Since we're in the midwest with cold winters, the battery heater (and heat pump) were an absolute need-to-have for us, and it is an additional reason why the Hyundai Kona sibling model was eliminated from our potential vehicle selection since the battery heater wasn't even an option for the US Kona, though I believe the Canadian version has it. There seem to be some odd choices being made by Hyundai & Kia on these early models.
