The Lumia 940 is expected to mark the debut of Windows 10 on a smartphone - arguably Microsoft's last chance to grab any thunder away from its giant iOS and Android rivals.
The handset itself will also pack in some tasty specs too, if past rumours prove to be true. Those include a Snapdragon 810 processor, 3GB of RAM, and a 5.7in 2K screen, all wrapped up in a polycarbonate shell.
A 20MP camera, iris scanner and USB Type-C port are also all on the cards, though we'll have to wait for anything official before we drool over the specs too much.
