Microsfot Lumia 640 640XL XL-5

We've been waiting for Microsoft to launch a flagship Lumia handset since it acquired Nokia's smartphone business, and now the software giant reportedly has not one but two on the horizon. These are the alleged specifications that have already leaked out.

According to smartphone blog Unleash the Phones, the two devices are codenamed "Cityman" and "Talkman" — both of which are names we've heard before. They're top-of-the-line flagships, but one is a larger phablet designed to compete with the likes of the Galaxy Note.

That's the Cityman, and according to the specifications, it will pack a 5.7-inch Quad HD display, a 64-bit octa-core processor from Qualcomm (either the Snapdragon 808 or the Snapdragon 810), 3GB of RAM, and 32GB of internal storage.

The device is also expected to offer a microSD card slot, a 20-megapixel rear-facing camera with three flash LEDs, a 5-megapixel front-facing camera, and a 3,300mAh battery.

The Talkman is slightly smaller at 5.2 inches, but it still boasts a Quad HD resolution, according to the report. Most of its other internals are also said to be the same as the Cityman's, only it will reportedly have a slightly slower hexa-core processor — also supplied by Qualcomm.

Microsoft vowed not to release any flagship Lumia smartphones until Windows 10 was ready to make its public debut. It's possible these devices will launch alongside Windows 10 for smartphones in the coming months, then, but Unleash the Phones doesn't offer a release date.

There is one other interesting tidbit in the report, however: sources say that Microsoft will also announce a new Windows 10 feature similar to Apple's Handoff for iOS and OS X, which will allow users to begin tasks on their smartphone and continue where they left off on them on their desktop — and vice-versa.

The feature may also allow users to send and receive messages and take calls on their PCs.
