Is there going to be any market share for a more expensive Cold climate heat pump?

Has the heat pump performance at close to 0'F actually been proven in real life experiences?

I guess it will take that special customer with a high electric rate + Cold climate to make this their selection.

Any thoughts on this product actually getting a noticeable market share in residential heat pumps?
