Microsoft will almost certainly have some new flagship Windows 10 devices to show off when its mobile operating system launches sometime this fall. We already know that it will work on older devices (see our gallery above), and you can run early test builds on many of them now, but Windows 10 Mobile will also add new features that take advantage of specific hardware. That includes the new Continuum feature, for example, which will allow you to connect your phone to a monitor for a more full-fledged computing experience in some apps. What sort of phones are coming?

Some leaks have pointed to at least one with an advanced camera, perhaps a successor to the Lumia 930 or the Lumia 1020. Now, @evleaks has some more information: the code names of Microsoft’s new devices. In a recent tweet, Evan Blass, the man behind @evleaks, said internal devices are currently named Guilin, Honjo, Saana and Saimaa. Those are in addition to known code names for phones dubbed Cityman and Talkman, Blass said.

We don’t know what these phones will offer just yet, but we’ll keep our ears to the ground for new information. Fall is approaching quickly, and it sounds like Microsoft has a lot to show off.
