Further confirming the claims, Tom Warren from The Verge in a tweet said, "Oh and HTC is working on a Windows Phone version of the One. Should be out later this year." Unfortunately, there is no specified time frame revealed for the launch of Windows Phone 8.1-based One (M8).
It's worth noting that we are yet to hear any official announcement from the company regarding launch of the smartphone.
The report suggests that the One (M8) smartphone's Windows Phone version will come with same specifications as the Android version of the handset.
