Later this year, Microsoft will announce their first flagship Lumia smartphones in well over a year, and according to a detailed report from Windows Central, these devices will be packed with the latest specifications and features.

To start with, Microsoft is expected to release two flagship devices: the "Talkman" and the "Cityman", which will perhaps be known officially as the Lumia 950 and Lumia 950 XL respectively. Naturally they will be running Windows 10 Mobile, and they're expected to be unveiled in September.

The smaller of the two devices, the Talkman, will come with a 5.2-inch 1440p display along with a Snapdragon 808 SoC, 3 GB of RAM and 32 GB of expandable storage. There will also reportedly be a 20-megapixel camera on the back, a 5 megapixel selfie camera, and a 3,000 mAh removable battery.

The Cityman will feature mostly the same specifications as the Talkman, although the display is larger at 5.7-inches and the device will be powered by a Snapdragon 810 SoC. Additionally, the battery is larger at 3,300 mAh, and Qi wireless charging is integrated into the body. Both the Cityman and Talkman will come with a USB Type-C connector.

Perhaps most interestingly, both devices will allegedly feature an infrared iris scanner that will work with Windows Hello to unlock them in less than a second. The functionality is not expected to be available at launch, although it will become available following a software update several months after release.

The Cityman (Lumia 950 XL) is expected to support two additional accessories: a smart cover with a circular cutout for viewing notifications, and a Surface Pen for annotating and drawing on the display. The Pen, which looks "exactly the same" as the Surface Pro 3's silver Surface Pen, will clip to the smart cover for storage.

Windows Central's report also includes information on an optional $99 accessory codenamed "Munchkin", which connects to the devices through USB Type-C and acts as a dock for Microsoft's Continuum feature.

Microsoft is expected to unveil their new flagship Windows 10 Mobile handsets at IFA in September, with a release date scheduled around a month later. It won't be too much longer before we get to see what Microsoft has in store for their next generation of smartphones running a revamped and refreshed operating system.
