Thought I would share the response I got from Mophie about a wireless charging case for the HTC 10. If it doesn't have wireless charging (Which seems likely given the recent information posted here and elsewhere), this may work as a good alternative.

Dear
xxxxx@xxx.com
We traditionally have always had compatible products close to the launch of our premier partners' products. As of now, we do not have word on when and if we will be creating a wireless charging case for the HTC 10.
However, we do our best to ensure we are always ready for any form factor changes that any of our partners may have and we will continue to do so. It is our top priority and our passion.
Thanks for sticking with us.
Thank you,
Customer Service Advocate
