Hello Tyhbmi,
Thank you for posting in Microsoft Community.
I appreciate you raising this inquiry to us and to answer your question:
At this time, Microsoft has not announced any plans to release a new version of the Wireless Display Adapter. As for availability, I recommend checking with your local retailers or online stores periodically for updates on when they will have the product back in stock. You can also check the Microsoft Store website for availability.
Thank you for continuously loving Microsoft, we deeply appreciate that. I hope it helps!
Best regards,
Rolando S.
